1.Concept
Food-grade materials are polypropylene that meets safety standards, and plastics that package food. The so-called safety standard is that the degraded components do not threaten human health.
2.Advantage
The pp material is a very common plastic. It can be made into a variety of plastic packaging, such as disposable lunch boxes, plastic bags, edible plastic parts and so on. It is safe, non-toxic and, most importantly, has excellent high temperature resistance. It can be heated in a microwave oven. It can also be refrigerated in the refrigerator. It is very versatile.
3.Future prospects
The application of plastic products in the packaging field began in the 1930s. Imperial Chemical Industry Corporation (ICI) invented polyethylene (PE), which was mainly used for plastic film packaging, and later gradually derived low density polyethylene (LDPE) and High density polyethylene (HDPE), these materials are mainly used in plastic containers. After World War II, polypropylene (PP) and polyethylene terephthalate (PET) were successfully developed. PP is widely used in the packaging of automobiles, household appliances, plastic pipes and furniture. PET is mainly used in beverage bottles and packaging. film. With the continuous development of production technology, there are more and more types of plastic packaging materials, and the scope of application is also wider and wider. Due to its light weight, good electrical insulation, imperviousness, impermeability, good chemical stability and strong plasticity, plastic packaging has become a promising sub-sector in the packaging industry and has been widely used in beverages. Condiments, daily chemicals, edible oils, alcohol, snack foods and pharmaceuticals.
The market for original applications such as beverages, condiments, daily chemicals, edible oils and snack foods has been expanding, especially in the beverage manufacturing industry. From 2006 to 2014, the annual compound growth rate of industry sales revenue was 18.89%, driving PET bottles. The market demand for plastic packaging containers continues to grow. At the same time, with the improvement of production technology and technology level, the application fields of the plastic packaging industry will continue to expand, bringing new market growth points for plastic packaging containers such as PET bottles. The rapid growth of the downstream market and the continuous expansion and development of the application field will bring a broad space for the development of plastic packaging containers such as PET bottles.
The barrels made of food-grade PP materials are welcomed by the majority of packaging companies and food factories. They are promising in the future. According to customers, the main reasons for selling are mainly strong sealing, strong anti-corrosion, reusable advantages, and long-distance The taste of the food can be maintained during transport and can be transported in a frozen environment.
