Is the paper packaging of food sealed?

January 03, 2023

When it comes to paper packaging, I believe everyone is familiar with it. As a kind of paper packaging, paper tube has attracted more and more attention in the industry, especially in the field of food packaging. For those who have not used the paper tube packaging, they must want to know whether the food paper tube packaging is airtight. Let's get to know.

The production process structure of paper tube packaging is complex, and the packaging forms are more and more diversified. At present, there are two main forms of paper tube packaging used in the food industry: one is full paper tube, which is made of paper; The other is the composite paper cylinder, which is made of paper, aluminum foil, metal and other composite materials.

For the whole paper packaging, the sealing performance is not good because all the paper is used as the raw material. For most food industries, in practical applications, the inner bag packaging is used first, and then the paper tube packaging is used. Nowadays, the upper and lower hems and inner and outer inserted core structures of full paper tube packaging applied in the food industry are common.

Compared with the full paper tube, the composite paper tube packaging has excellent sealing performance, which can play a role in waterproof and moisture-proof, and can meet the sealing requirements of most foods for packaging. Nowadays, composite paper packaging is widely used in the food packaging field, and is favored by more and more food industries.
