Public Participation in Environmental Impact Assessment for the Fully Automated Printing and Packaging Materials Clean Production Line Project - Second Public Announcement
In accordance with the "Public Participation in Environmental Impact Assessment" (Ministry Order No. 4, effective January 1, 2019), this environmental impact assessment is being publicly announced to understand public opinion and suggestions on this project and to accept public supervision. Details are as follows:
I. Project Overview
(I) Project Name: Fully Automated Printing and Packaging Materials Clean Production Line Project
(II) Project Overview: Guangdong Xingyin Packaging Materials Co., Ltd. plans to construct a "Fully Automated Printing and Packaging Materials Clean Production Line Project" in the northeast of plot C03, Nanshanwan Industrial Park, Haoxiang District, Shantou City. The total investment is 75 million yuan, covering an area of 13503.79 square meters, with a total construction area of 15739.56 square meters. The project plans to construct two factory buildings, one office and staff building, one gatehouse, and other supporting environmental protection facilities, with an annual output of 5000 tons of packaging films and bags.
II. Potential Environmental Impacts and Proposed Environmental Protection Measures
1. Construction Phase:
The main pollutants during the construction phase of this project are construction noise, dust, construction solid waste, and construction wastewater. As long as the project's construction unit strictly strengthens construction management, conducts scientific construction, and follows the requirements of this report to control environmental pollution during construction, the environmental pollution generated during the construction period can be controlled, and will not have a significant adverse impact on the surrounding environment.
2. Operation Phase
(1) Waste Gas: The main waste gases of this project are ammonia and organic waste gases from ink mixing, printing, glue mixing, lamination, and the storage of raw and auxiliary materials and hazardous waste. The ink and glue mixing rooms, printing workshop, lamination workshop, solvent warehouse, ink warehouse, glue warehouse, and hazardous waste temporary storage room of this project are sealed and under slight negative pressure. The generated waste gas is collected through pipelines, treated by RTO, and then discharged. The RTO device for organic waste gas treatment in this project needs to use natural gas for preheating every day. The preheating process produces a small amount of fuel waste gas that meets the emission concentration limits for "gas-fired boilers" in Table 2 of the Guangdong Provincial "Emission Standards for Air Pollutants from Boilers" (DB44765-2019). According to the "Notice on the Key Work of Comprehensive Remediation of Industrial Kilns and Boilers in 2021" (Yuehuan [2021] No. 461) issued by the Guangdong Provincial Department of Ecology and Environment, "new gas-fired boilers in the province should adopt low-nitrogen combustion technology, and nitrogen oxides should reach 50mg/m3"; ammonia gas produced during the production process can meet the requirements for new, expanded, and renovated projects in Table 1 of the "Emission Standard for Malodorous Pollutants" (GB14554-93) and the emission standard values for malodorous pollutants in Table 2; VOCs can meet the emission limit values for VOCs from exhaust pipes in Table 2 of the Guangdong Provincial Local Standard "Emission Standard for Volatile Organic Compounds in the Printing Industry" (DB44/815-2010) and the concentration limit values for unorganized emissions in Table 3.
(2) Wastewater: This project is within the sewage collection area of the Haoxiang Branch of the Shantou City Nan District Sewage Treatment Plant. After pretreatment in a three-stage septic tank, the domestic sewage meets the Class III standard of the second phase of the Guangdong Provincial Local Standard "Emission Limits for Water Pollutants" (DB44/26-2001), and is discharged into the Haoxiang Branch of the Shantou City Nan District Sewage Treatment Plant for deep treatment through the municipal sewage pipe network, and finally discharged into the Haoxiang River. The effluent quality of the Haoxiang Branch of the Shantou City Nan District Sewage Treatment Plant can achieve the standard discharge, and the operation of the Haoxiang Branch of the Shantou City Nan District Sewage Treatment Plant is good, and it can accept and treat the wastewater of this project. Therefore, the wastewater discharge of this project has a small impact on the surface water environment.
(3) Noise: The main high-noise equipment of this project includes gravure printing machines, gravure printing machines, inspection machines, laminating machines, solvent-free laminating machines, slitting machines, bag-making machines, and RTO devices. After taking corresponding noise reduction measures, the noise at the east boundary of this project is expected to reach the Class 4 standard in "Emission Standard for Environmental Noise at the Boundaries of Industrial Enterprises" (GB12348-2008), and the noise at the south, west, and north boundaries can reach the Class 3 standard in "Emission Standard for Environmental Noise at the Boundaries of Industrial Enterprises" (GB12348-2008).
(4) Solid Waste: Domestic garbage from this project will be transported by the sanitation department; defective products and scraps will be sold to material recycling units for comprehensive utilization; waste rags, waste ink, waste adhesives, raw material packaging barrels, waste oil, and their packaging barrels will be properly collected and recycled by qualified units.
(5) Groundwater and Soil: This project will carry out anti-seepage work in the hazardous waste temporary storage room, production workshop, and other sites, and prevent the open-air stacking of solid waste to ensure that the construction and operation of this project will not have a significant impact on the groundwater and soil environment.
(6) Environmental Risks: Environmental risk accidents of this project include material leakage, fire accidents, and failures of pollution control measures. This report uses a qualitative method to assess the above risks and proposes risk prevention measures and contingency plans. Under the premise that the construction unit strictly implements the accident prevention and emergency measures proposed in this report and strengthens management, the potential environmental risks can be minimized, and once an accident occurs, the impact range can be controlled to a smaller extent, reducing losses. The construction unit should formulate an emergency plan for sudden environmental events, strictly implement risk prevention measures, and conduct regular emergency drills to prevent accidents.
III. Environmental Impact Assessment Conclusion
This project complies with industrial policies, land use planning, and relevant environmental protection plans. The construction of the main project should strictly follow the pollution control measures required in the report, ensure that the funds are in place, achieve the "simultaneous" implementation of the main project and pollution control measures, strengthen the operation and maintenance of environmental protection facilities, establish and improve the in-plant environmental protection agency and standardized environmental management system, and ensure that all pollutants meet the emission standards. The project should take emergency measures in case of accidents. Under the above-mentioned conditions, the construction of this project will not change the environmental function of the project area. From the perspective of environmental protection, the construction of this project is feasible.

Understanding the production process and key points of stand-up pouches
I. Production Procedures 1. Preparation: Install the horizontal heat-sealing knife, bottom heat-sealing knife, and reinforced heat-sealing knife. Install the punching device. 2. Film threading, EPC setting, aligning the bag edge and pattern. 3. Adjust the bottom heat-sealing knife, input the length dimension. The knife position and direction must be aligned. Adjust the knife using the upper knife as a reference. Check if the round hole is round. Set the photoelectric sensor. 4. Install the bottom film and adjust it to the middle fold. Adjust the bottom film punching. 5. Adjust the horizontal heat sealing to align the heat sealing knife position with the printing position. 6. Adjust the reinforced heat sealing block to apply pressure at the four-layer intersection. 7. Adjust the cutting knife and the edge material cutting device. 8. Confirm and adjust the bottom punching position and bottom heat sealing position. Confirm and adjust the position of the horizontal heat sealing knife and the reinforced heat sealing block. Confirm the heat sealing strength and adjust the heat sealing temperature. II. Production Key Points 1. The bottom film tension should not be too high. If the tension is too high, the round holes on the bottom will deform. The general tension is 0.05~0.2 MPa. 2. For the first set of heat-sealing knives, use higher pressure and lower temperature. For the second and third sets, use normal temperature and pressure. 3. Adjust the spring pressure of the reinforced heat-sealing block to zero, allowing only the self-weight of the heat-sealing device to take effect. 4. Generally, use 50° hardness silicone rubber plates. Use 70° plates when the heat-sealing area is smaller. 5. When heat sealing, if the bottom round hole becomes elliptical, increase the waiting time by 100 minutes. 6. The bag making speed is generally 50~100 bags/minute. Hopefully, the above understanding of stand-up pouches from the editor will be helpful to you.

Precautions for high-temperature steaming bag production process
1. Balanced substrate thickness, good corona treatment effect, and high heat shrinkage resistance. Commonly used high-temperature retort pouch substrates include PET, NY, Al, and RCPP. The corona treatment effect of these substrates directly affects the composite strength of the high-temperature retort pouch; during the high-temperature retort process, the substrates will shrink to varying degrees. If the corona treatment of the material does not achieve the expected effect, the composite strength is low, and there is not enough force between the layers of the composite bag to prevent substrate shrinkage, resulting in severe delamination of the bag layers after high-temperature retorting. Generally, the surface tension of PET and NY used for high-temperature retort pouches should reach 50 mN/m, and RCPP should reach 40-42 mN/m. In addition, some additives in the substrate, such as anti-blocking agents, anti-slip agents, and antistatic agents, accelerate release to the surface at high temperatures, which may lead to a decrease in adhesion. Since high-temperature retort pouches are basically in water during the sterilization process, when measuring the substrate shrinkage rate, the substrate shrinkage rate should be measured at 120℃ for 30 min. The shrinkage rate should be small and stable, especially for BOPA film, RCPP film, and SCPP film. The longitudinal and transverse moisture-proof shrinkage rate is recommended not to exceed 1.5% before it can be called a retort-grade film. The balanced thickness of each layer of the material should be uniform, and the thickness deviation should not exceed 7%, and the physical and mechanical performance indicators should meet the requirements. For aluminum foil products, in addition to their mechanical performance parameters, the surface of the aluminum must be dry, and the cleanliness of A and B must meet the standards, that is, they must be wet when checked with distilled water, and the number of pores must be as small as possible. Well, the storage time before use should not exceed three months. To improve the composite strength, the BOPA in the middle composite should use double-sided corona treatment, and the corona value should not be less than 50 dynes. 2. Compatibility of cooking inks, adhesives, and substrates The production of composite packaging bags is a process of superimposing the various properties of various materials, so it requires that the substrates, inks, adhesives, etc., have good compatibility and high temperature, humidity, and heat resistance. The degree of matching between them is very important. If the matching is not good, the processed products may have poor appearance or delamination during the retorting process. According to the adhesion theory, when the adhesive and the adherend have the same surface tension and the same polarity, the interfacial tension is minimized, and the adhesion strength is the highest. Therefore, the surface condition of the ink and adhesive after curing and film formation and the surface condition of the printing substrate may vary depending on the manufacturer's products. Whether the groups on different surfaces can be attracted to form intermolecular forces or chemical reactions to form chemical bonds. It determines whether various surfaces have good adhesion. Therefore, when making retort pouches, the resin type of ink and adhesive should be fully considered to avoid poor overall performance of the retort pouch due to incompatibility between ink, adhesive, and printing substrate. The inks or adhesives used for high-temperature retort pouches are generally two-component polyurethane resin types. The heat resistance of inks or adhesives mainly depends on the heat resistance and moisture resistance of the polyurethane resin. High temperature improves the reaction characteristics of ink and adhesive. If the heat resistance and moisture resistance of the ink and adhesive are insufficient, hydrolysis will occur at high temperatures, and the composite strength will decrease. From the characteristics of the polyurethane resin system, the amino and ester groups in the resin have strong polarity and are easily eroded and hydrolyzed by moisture under wet heat conditions. The hydrogen bonds between the polyurethane resin and the substrate surface are easily broken, reducing the bonding strength and even causing the bonding layer to peel off. At present, the inks and adhesives used for high-temperature retort pouches are modified with resins or additives to improve the adhesion and heat resistance of the inks and adhesives. Therefore, the quality of the modified resin used in the ink and adhesive determines the quality of the ink and adhesive. Select RCPP and SCPP for the heat-sealing layer according to different retort temperatures. RCPP or SCPP is usually used as a heat-sealing material above 121℃, and the thickness must be greater than 60 μm. It is generally recommended to use imported products. The inner layer of imported RCPP contains rubber components, which are block copolymers and impact-resistant polypropylene. 3. Control of curing time and adhesive application amount Due to the special sterilization method and use conditions of high-temperature retort pouches, high-temperature retort pouches need to have good composite strength to reduce the influence of wet heat conditions on the quality of high-temperature retort pouches, and the composite strength is closely related to the adhesive application amount and curing time. The adhesive application amount of high-temperature retort pouches generally needs to reach more than 4 g/m2; the curing time is another important factor affecting the composite strength. The curing time of high-temperature retort pouches generally needs to reach more than 72 h. Sometimes, although this time is not reached, the adhesive layer is dry after the bag is peeled off, and the curing seems to be complete. However, in the actual high-temperature processing process, due to the residual stress inside, it will still be far different from the product with sufficient curing time in terms of heat resistance and moisture resistance, and in the subsequent bag-making process, it is easy to produce heat-induced delamination. Therefore, in the production process of high-temperature retort pouches, we should not blindly pursue speed, but should prioritize the quality of high-temperature retort pouches and strictly follow the process requirements for production. 4. Gold and silver inks are not suitable for high-temperature retort pouches Gold and silver inks are very prone to penetration of pigments, such as crimson, bright blue, and purple inks. When they encounter water and the temperature is high, dissolution is certain. The copper powder and aluminum powder used in gold and silver inks are metals with relatively high activity, and they are easily chemically reacted with water, oil, and oxygen at high temperatures. After oxidation reaction, the appearance shows blackening, greening, or even fading. Therefore, gold and silver inks and inks that are prone to penetration cannot be used for high-temperature retort pouch products.

Advantages of Spout Pouch Packaging
Spout pouches are a type of liquid packaging that replaces rigid packaging with flexible packaging. The structure of a spout pouch mainly consists of two parts: a spout and a self-supporting pouch. The stand-up pouch is made of multi-layer composite plastic materials to meet the requirements of different food packaging properties and barrier properties. The spout part can be regarded as an ordinary bottle mouth with a cap screwed on. The two parts are tightly bonded by heat sealing (PE or PP) to form a squeezed, sucked, poured, or pressed liquid package, which is a very ideal new type of liquid packaging. Compared with ordinary packaging forms, the biggest advantage of spout pouches is their portability. Spout pouches can be easily placed in backpacks or even pockets, and their volume can be reduced as the contents decrease, making them more convenient to carry. The soft drink packaging on the market mainly includes PET bottles, composite aluminum foil bags, and cans. In today's increasingly obvious homogenized competition, packaging improvement is undoubtedly one of the powerful means of differentiated competition. Spout pouches combine the reusable packaging of PET bottles and the fashion of composite aluminum foil bags. At the same time, it also has unparalleled advantages in printing performance compared with traditional beverage packaging. Due to the basic shape of the self-supporting pouch, the spout pouch has a significantly larger display area than PET bottles and better than non-stand-up Tetra Paks. It can be sterilized at high temperatures and has a long shelf life. It is also made of single recyclable low-carbon composite materials, making it the ideal sustainable solution for liquid packaging. It has unique advantages and wider applications in the fields of juice, dairy products, soy milk, vegetable oil, health drinks, jelly foods, pet food, food additives, traditional Chinese medicine, daily chemical products, and cosmetics.
