Food airtight jars are indispensable containers for storing food in our daily life. Choosing the right material can ensure the quality and taste of food, and at the same time protect our health. So, which material is more suitable for making food airtight jars, such as pmma, pet, and as?
First of all, the pmma material has excellent transparency and gloss, and the food airtight cans produced can well show the appearance of the food. In addition, pmma material also has the advantages of strong acid and alkali resistance and heat resistance, will not release harmful substances, and has a good effect on the protection and maintenance of food quality. However, the relative density of pmma material is relatively high, the processing is difficult, and the production cost is also high.
Secondly, the pet material has the characteristics of good impact resistance and strong flexibility, and it is also very suitable for making food airtight cans. Moreover, the pet material is relatively light, and the production cost is relatively low. However, food airtight cans made of pet materials are sensitive to temperature changes and acid-base foods, are prone to static electricity, and may release harmful substances such as heavy metals, and their protection effect on food is not as good as that of pmma materials.
Finally, food airtight cans made of as material have good wear resistance, weather resistance and toughness. Moreover, the transparency of the as material is relatively high, which can better display food. However, due to the low flexibility of the as material, the processing difficulty is high, and the production cost is high, the usage rate in the production of food airtight cans is low.
To sum up, in terms of production, performance, cost and other considerations, food airtight cans made of pmma material are relatively superior choices. Of course, for different types of food, it is also necessary to choose different materials. Only by selecting the appropriate material according to the specific situation can we better meet the needs of different foods and ensure the quality and health of the food.
