Behind the term composite membrane lies the perfect combination of two or more materials, which are woven together into a "protective net" with high strength and puncture resistance. This "net" plays an indispensable role in many fields such as food packaging, medical device packaging, pharmaceutical packaging, and daily chemical packaging. Today, let us discuss the key points that should be paid attention to when choosing food packaging composite film.
Food packaging composite film is like the "patron saint" of food, guarding the freshness and deliciousness of food. Whether it is steamed and vacuum-packed food, or frozen, biscuits, chocolate and other types of food, you can find a matching composite film "partner". However, when choosing these "partners", we need to pay attention to the following points:
First of all, temperature resistance is a major test for food packaging composite films. It must be able to remain tough in high and low temperature environments to ensure food stability and safety. Only such "partners" can make us feel at ease.
Secondly, barrier properties are also an important criterion for judging an excellent food packaging composite film. It must be able to effectively block the intrusion of oxygen, water vapor and various odors, and also allow the food to maintain its original freshness and taste. Block the outside and protect the inside! It's like putting a "protective suit" on the food, allowing it to remain perfect in isolation from the outside world.
Furthermore, mechanical performance is also an aspect that cannot be ignored. Food packaging composite film needs to withstand various physical and mechanical effects during packaging, transportation, storage, etc. Therefore, it must have strong tensile strength, tear resistance, compression resistance, abrasion resistance, waterproof performance, etc. Only such a "partner" can demonstrate its strength in various challenges.
In general, the material structures of food packaging composite films are rich and diverse, and we need to make reasonable selection and design according to the special requirements of specific products. Only in this way can the safety, freshness and appearance of food be ensured.
