Our liquid aseptic packing cartons are made of the best renewable natural resource - wood fiber. The paper board made of this kind of fiber has enough strength to make the packing extremely stable. The paper board suppliers we select have strict production management and environmental protection standards in their factories and woodlands, and are in strict accordance with stipulations with respect to ecological protection and development and utilization of forest resources. The ultra-thin aluminum foil and PE layer of the packing materials can effectively block any influence of light, dampness, oxygen and other bad factors from the outside to the products, so as to ensure product quality and safety during all chains from production till end users.
Lamination Structure:
Layer 1: Outer layer is to resist moisture and external liquid agents
Layer 2: Printing ink is to provide decoration
Layer 3: Paperboard to ensure package stiffness
Layer 4: Lamination layer is to provide adhesion between paperboard and aluminum foil
Layer 5: Aluminum foil to provide a barrier against light and gaseous exchanges
Layer 6: Tie layer is to provide adhesion between the aluminum foil and inside multilayer
Layer 7: Inside multilayer is to seal the container and keep the flavor of the filled product
