Composite pouches

Composite pouches are a type of complex packaging that is made by combining different layers of materials and gluing them together through the lamination process. This type of packaging is used to preserve products against various environmental factors. Each layer in this three-layer composite envelope has its own characteristics and tasks to maintain quality and convey the necessary information about the product.
Composite envelopes are produced in different types including white paper, kraft paper and resistant (synthetic) paper.
The materials of these envelopes usually include propylene sack + polyethylene + paper or propylene sack + paper + BOPP.
Composite envelopes have properties such as moisture resistance, beauty, high quality printing, impact resistance and 3 or 4 layers.
The uses of composite envelopes include packing animal and poultry feed, dry milk, chemicals, agricultural fertilizers, food and industrial materials, and advertising banner wrappers.
