The main component of the composite paper can is paper. In order to meet the requirements of containing liquid and improving sealing, plastic film and aluminum foil are laminated on the basis of the main material to avoid being soaked by the solution. When it comes to sealing, composite paper cans have better sealing than other ordinary paper cans, which can protect products from moisture and oxidation.
For some products with special requirements for the sealing of paper cans, the use of composite paper cans can better meet the needs of safe circulation of products. Although paper cans are a kind of paper packaging, they can also achieve the same sealing effect of plastic packaging and metal packaging. This is also the reason why composite paper cans are more and more popular in the market in recent years. For paper cans used to hold food, The inner membrane shall be made of food grade aluminum foil to ensure food quality and safety.
Structural features of composite paper tank:
The composite paper can be made of 3-5 layers or even more layers according to the packaging requirements, with a thickness ranging from 1mm to 5mm, which can meet the packaging requirements of various leisure foods, such as potato chips, dried fruits, chicken essence, chicken powder, rice, sesame powder, spirulina and other solid and powdery objects. Composite paper can packaging belongs to natural green packaging, which can be recycled and degraded.
Compared with other traditional packaging processes, the paper bottom heat sealing technology of composite paper cans can save more raw materials, reduce costs and create greater benefits for customers.
The composite paper can belongs to a kind of paper can. Therefore, the composite paper can also takes paper as the main raw material, but the difference from other types of paper cans is that the composite paper can is composed of paper and other materials (aluminum foil), which is not only safe and environmentally friendly, but also has good sealing, which is also the special feature of the composite paper can. This is also the main reason why composite paper cans are favored by the food industry.
Food composite paper cans are usually composed of 3-5 layers or even more layers, with a thickness of about 1mm-5mm. Therefore, food composite paper cans have good sealing and moisture-proof effect. Moreover, the food composite paper can also has excellent protection performance, can withstand positive pressure or negative pressure, can be used for vacuum packaging and nitrogen filling packaging, can also fill commodities of various shapes, and has low noise during filling. The composite paper can has various shapes and structures, which can achieve good display effect.
The above is an introduction to the raw materials for making composite paper cans and the sealing performance. It can be seen that the raw materials of composite paper cans are mainly paper. It can adjust the structure according to the differences of contained articles, so as to meet the packaging requirements and achieve better sealing effect at the same time.
