Precautions for the production process of high temperature cooking bags
2022-05-171. The thickness of the base metal is balanced, the corona treatment effect is good, and the thermal shrinkage rate is high
Details
Commonly used high temperature cooking bag substrates are PET, NY, Al, RCPP, etc. The corona treatment effect of these substrates directly affects the composite strength of the high-temperature cooking bag; during the high-temperature cooking process, the substrate will shrink to varying degrees. The corona treatment of the material did not achieve the expected effect, the composite strength was low, and there was insufficient force between the composite bag layers to hinder the shrinkage of the substrate, resulting in serious delamination of the bag layer after high-temperature cooking. In general, the surface tension of PET and NY used in high temperature cooking bags should reach 50mN/m, and RCPP should reach 40~42mN/m. In addition, certain additives in the substrate, such as anti-blocking agents, anti-slip agents, and anti-static agents, accelerate their release to the surface at high temperatures, which can lead to decreased adhesion. Since the high temperature and high temperature cooking bag is basically in water during the sterilization process, when measuring the shrinkage rate of the substrate, the shrinkage rate of the substrate should be measured at 120 °C for 30 minutes. The shrinkage rate should be small and stable, especially for BOPA film, RCPP film and SCPP film. The moisture-proof shrinkage rate in the longitudinal and transverse directions is recommended not to exceed 1.5% before it can be called a cooking grade film.
The balance thickness of each layer of the material should be uniform, the thickness deviation should not exceed 7%, and the physical and mechanical performance indicators should meet the requirements.
To use aluminum foil products, in addition to its mechanical performance parameters, the surface of the aluminum must be dry, A and B and clean must meet the standards, that is, when checking distilled water, they must be wet, and the number of pores must be as small as possible. Well, the storage time before use cannot exceed three months. In order to improve the composite fastness, double-sided corona should be used for the middle composite BOPA, and the corona value should not be less than 50 dynes.
2. Compatibility of cooking inks, glues and substrates
The production of composite packaging bags is a process of superimposing various properties of various materials, so substrates, inks, glues, etc. are required to have good compatibility and high temperature, humidity, and heat resistance. The degree of matching between them is very important. If the match is not good, the processed product may have poor appearance or delamination during cooking. According to the bonding theory, when the adhesive and the adherend have the same surface tension and the same polarity, the interfacial tension is the smallest and the bonding strength is the highest. Therefore, the surface condition of the ink and glue after curing into a film and the surface condition of the substrate may be different for different manufacturers' products. Whether groups on different surfaces can be attracted to form intermolecular forces or chemically react to form chemical bonds. It determines whether various surfaces have good adhesion. Therefore, the resin type of ink and glue should be fully considered when making steaming bags to avoid poor overall performance of steaming bags due to incompatibility of inks, glues and substrates.
The ink or glue used for high temperature cooking bags is generally two-component polyurethane resin type. The heat resistance of ink or glue mainly depends on the heat resistance and moisture resistance of the polyurethane resin. The high temperature improves the reaction characteristics of the ink glue. If the temperature resistance and moisture resistance of the ink and glue are insufficient, hydrolysis will occur at high temperature, and the composite strength will be reduced. Judging from the characteristics of the polyurethane resin system, the amino and ester groups in the resin are extremely polar, and are susceptible to moisture erosion and hydrolysis under humid and hot conditions. The hydrogen bond between the polyurethane resin and the surface of the substrate is easily destroyed, which reduces the bonding strength, and the bonding layer even falls off. At present, the inks and glues for high-temperature cooking bags are modified with resins or additives to improve the adhesion and heat resistance of the inks and glues. Therefore, the quality of the modified resin used in the ink and adhesive determines the quality of the ink and adhesive. The RCPP and SCPP of the heat sealing layer are selected according to different cooking temperatures.
RCPP or SCPP are usually used for heat sealing materials above 121℃, and the thickness must be greater than 60um. Imported products are generally recommended. The imported RCPP inner layer contains -
Advantages of nozzle bag packaging
2022-05-17The nozzle bag is a water-spraying liquid packaging that replaces the rigid packaging in the form of flexible packaging. The structure of the nozzle bag is mainly divided into two parts: the nozzle and the self-supporting bag. The stand-up bag is made of multi-layer composite plastic materials to meet the requirements of different food packaging performance and barrier performance. The nozzle part can be regarded as an ordinary bottle mouth with a straw cap screwed on. The two parts are tightly combined by heat sealing (PE or PP) to form a liquid packaging that is squeezed, sucked, poured or pressed out, which is a very ideal new type of liquid packaging.
Details
Compared with ordinary packaging forms, the biggest advantage of spray bags is that they are easy to carry. The spray pocket can be conveniently placed in a backpack or even a pocket, and the volume can be reduced with the content, making it more convenient to carry. Soft drink packaging on the market mainly includes PET bottles, composite aluminum paper bags, and pop-top cans. In today's increasingly obvious homogeneous competition, the improvement of packaging is undoubtedly one of the powerful means of differentiated competition. The spout bag combines the repetitive packaging of PET bottles with the fashion of composite aluminum paper bags. At the same time, it also has the incomparable advantages of traditional beverage packaging in terms of printing performance. Due to the basic shape of the self-supporting bag, the spout bag has an obvious display area, which is larger than a PET bottle and better than a Tetra Pak pillow that cannot stand. High temperature sterilization, long shelf life. It is also made from a single recyclable low carbon composite material and is the most ideal sustainable solution for liquid packaging. It has unique advantages and wider applications in the fields of fruit juice, dairy products, soy milk, vegetable oil, health drinks, jelly food, pet food, food additives, traditional Chinese medicine, daily chemical products, cosmetics and other fields. -
Future development prospects of stand-up pouches
2022-05-17People's purchasing power for fast-moving consumer goods is also growing, and the rapid development of the fast-moving consumer goods market has also led to the rise of the food packaging industry. Nowadays, the types and uses of food packaging are very wide, and good packaging can make products establish a high-quality image, improve product competitiveness, and promote product sales.
Details
There are many ways to classify food packaging. According to the technical classification, it can be divided into: moisture-proof packaging, waterproof packaging, mildew-proof packaging, fresh-keeping packaging, quick-freezing packaging, breathable packaging, microwave sterilization packaging, aseptic packaging, inflatable packaging, vacuum packaging, deoxygenation packaging, blister packaging, paste Body packaging, stretch packaging, retort bag packaging, etc. The above-mentioned various packages are all made of different composite materials, and their packaging characteristics are corresponding to the requirements of different foods, which can effectively maintain the quality and stable functions of the food itself.
Among them, the stand-up pouch is considered to be one of the classics of modern packaging, and it is also a relatively novel packaging form. Take advantage of. There are five types of stand-up pouches: ordinary stand-up pouches, stand-up pouches with suction nozzles, stand-up pouches with zippers, spout-like stand-up pouches, and special-shaped stand-up pouches. In jelly, condiments and other products, in addition to the food industry, the application of some washing products, daily cosmetics, medical supplies and other products has gradually increased.
Products packed in stand-up pouches are very convenient for shoppers: because it is a soft plastic package, it is light in weight and not easily damaged, and the shopping bag will not be broken by hard packaging, and it is easier to waste than bottles. Plus zip-up pouches can be refilled; nozzle pouches make food easier to pour; perfect printing quality can help retailers in order to attract consumers' attention; stand-up pouches, cans, packaging are less restricted by regulations and more. The current stand-up pouch technology can already realize many dreams, which is an excellent market opportunity for soft plastic manufacturers. Some people in the industry also pointed out that with the introduction of high-capacity bagging automation equipment, the development potential of flexible packaging bags is increasing.
The nozzle bag became popular in the 1990s. It is a soft packaging bag with a horizontal support structure at the bottom and a suction nozzle on the top or side. It can stand on its own without any support, so it is named as a nozzle stand-up bag.
It is a relatively novel form of packaging, which has advantages in improving product grades, enhancing shelf visual effects, carrying light, easy to use, fresh-keeping and sealability.
The stand-up pouch is made of PET/foil/PET/PE structure laminated, and can also have 2 layers, 3 layers and other materials of other specifications. It depends on the different products of the package. The oxygen barrier protective layer can be added as needed to reduce the oxygen permeability. , extending the shelf life of the product. Ordinary stand-up pouches and general forms of stand-up pouches are in the form of four-sealed edges, which cannot be re-closed or re-opened; stand-up pouches with suction nozzles are more convenient to dump or absorb the contents, and can be re-closed and re-opened at the same time. The combination of ordinary bottle mouth; the imitation mouth type stand-up pouch combines the convenience of a stand-up pouch with a suction nozzle and the cheapness of an ordinary stand-up pouch, that is, the function of the suction nozzle is realized through the shape of the bag body itself, but the imitation mouth type stand-up pouch cannot be repeated. Sealing and opening; special-shaped stand-up pouches are new stand-up pouches of various shapes produced by changing on the basis of traditional bag types according to packaging needs, such as waist design, bottom deformation design, handle design, etc. main direction of development.
The packaging form of stand-up pouches is widely used in soy milk products. Compared with other packaging, the packaging of stand-up pouches is clean and convenient. You can open it if you want to drink it, and screw it up if you don’t want to drink it without waste. And it can meet the different sterilization and preservation conditions in the production of soymilk, not only 3 to 5 days under refrigerated conditions, but also about 1 month under normal temperature conditions. At the same time, soymilk for breakfast and ready-made soymilk also began to be packaged in stand-up pouches. -
Stand-up bags and zipper bags are favored by food companies
2022-05-17Food packaging not only carries the mission of containing and protecting food, it should also provide consumers with maximum convenience and ease of use with minimal impact on the environment. Xiangwei Packaging recommends two types of food packaging to food companies, namely stand-up pouches and zipper bags. These two kinds of packaging have been used in the field of food packaging in recent years due to their advantages of convenience, ease of use, good shelf display and environmental protection. favor.
Details
1 stand up pouch
A stand-up pouch is a flexible packaging bag with a horizontal support structure at the bottom. It does not need to rely on any support, it can stand independently whether the bag is open or not. Stand-up pouches have excellent shelf display. In addition, in order to meet the needs of individual consumers, self-supporting bags can also add personalized design elements, such as handles, curved outlines, resealable zippers, etc., which greatly enhances consumers' desire to buy. At present, stand-up pouches have been widely used in the packaging of food, juice drinks, smoked jelly, condiments, pet food, etc.
2 zipper pockets
The zipper bag refers to adding a zipper to the original flexible packaging bag, so that the packaging bag has a resealable function, so that consumers can reseal uneaten food. In developed countries and regions such as Europe and the United States, zipper bags have been widely used in food packaging fields such as meat, cheese, frozen food, nuts, candy, cakes, etc. At present, our zipper bags are mainly used in betel nut, tea and other fields. The zipper bags used for food packaging mainly include three series: compression type, slider type and zipper strip type.
Although the development history of self-supporting bags and zipper bags in my country is not long enough, they have shown a good momentum of development. We have reason to believe that in the near future, these two flexible packaging forms will be more and more widely used in the field of food packaging.
