There are so many requirements for food plastic packaging, and there are so many demands!
Addictive spicy strips, summer thirst quenching milk tea, soft and delicious bread, fragrant roast duck... Most of the various foods we love in our daily lives cannot do without exquisite packaging. Have you ever paid attention to the material of the packaging? I believe everyone's first reaction is that most of them are packaged in plastic. So, what are the requirements for making plastic packaging? Due to the particularity of food, the packaging of food has stricter requirements compared to the packaging of other products.
One thing that I believe everyone can guess is that plastic used for food packaging materials should not only have the properties that general packaging materials should have, but also pay special attention to packaging hygiene issues, becoming an important means to ensure food hygiene, safety, and extend food storage life. So, what are the standards for plastic film used in food packaging? Firstly, it must fully comply with food packaging hygiene standards. The plastic box itself does not undergo the migration of toxic substances, is non-toxic, odorless, and odorless; Printing and box making can meet the above standards.
According to the packaging needs of different types of food, corresponding packaging materials are used. Plastic flexible packaging materials for food mainly include high molecular weight materials such as polyethylene, polypropylene, polyester, polyamide, etc. In order to maintain freshness and provide safe and hygienic food to consumers during circulation, it is necessary to conduct safety inspections on food packaging. There are many requirements for the performance of food packaging, such as barrier performance: Barrier performance includes the barrier against gas and moisture. A well sealed environment can reduce the probability of food spoilage and improve storage quality. Tensile performance is equally important: during the packaging process, the film is subjected to mechanical tension, and during transportation, the product is inevitably subjected to external forces such as compression, which requires the packaging film to have sufficient tensile strength to adapt to this environment.
How to choose food packaging materials? When choosing the outer packaging, you can refer to the packaging materials of food products on the market that have similar characteristics to your product; After comparing some similar products, choose the packaging type that is most suitable for your product in all aspects. Professional packaging manufacturers can help you quickly and accurately choose the appropriate packaging type for your products!
