As a kind of paper packaging, composite paper cans are currently a popular packaging form on the market. Composite paper cans integrate the advantages of green, environmental protection, and sealing. Especially their good sealing properties have attracted the attention of various industries, especially the food industry. How does the composite paper can achieve good airtightness?

Composite paper cans use paper and food-grade aluminum foil as raw materials. The can body usually has 3, 5 or more layers of composite, and the thickness is about 1mm-5mm. The bottom end of composite paper cans mostly adopt traditional paper bottom curling process, and the upper cover adopts metal easy-pull lid or aluminum foil easy-to-tear lid. Therefore, the composite paper can has good airtightness. Currently, composite paper cans are widely used in the food packaging industry.

Junxing Yimei has been focusing on the production of paper cans for more than 20 years. It has a strong R&D and innovation team and constantly develops new products to meet the customized needs of different customers for paper cans. In 2019, after continuous exploration and repeated experiments, Junxing Yimei's paper can custom manufacturer successfully developed a paper-bottom heat-sealing process composite paper can independently, which marks Junxing Yimei has stepped on a new level in the field of paper can packaging.

Different from the traditional paper bottom curling process, the paper bottom heat sealing process composite paper can inner film adopts food-grade aluminum foil + PE heat sealing, which has better sealing and can be filled with nitrogen, which reduces the contact between labor and the product and effectively reduces the risk of foreign matter.

Compared with the traditional paper bottom curling process, the paper bottom heat sealing process saves raw materials, reduces production costs, and reduces the weight of the paper can packaging. The successful research and development of Junxing Yimei's paper bottom heat-sealing process provides customers with solutions to reduce costs, creates greater value for customers, and wins the trust of customers.
