定义
The Barrier Core Layer is a critical component within multi-layer barrier vacuum pouch seal strips, engineered to create an impermeable barrier against oxygen, moisture, and other environmental contaminants. This layer is typically composed of specialized polymers or metalized films that prevent gas transmission, thereby extending the shelf life of packaged products by maintaining vacuum integrity and preventing spoilage.
工作原理
Operates on the principle of molecular barrier technology, where the dense polymer matrix or metalized coating creates a physical obstruction to gas molecules (primarily O2 and H2O). During the sealing process, this layer fuses with adjacent layers under heat and pressure, forming a continuous barrier that maintains vacuum conditions by preventing atmospheric gas ingress through diffusion.
材料
EVOH (Ethylene Vinyl Alcohol) copolymerPA (Polyamide/Nylon)metallized PET (Polyethylene Terephthalate)aluminum foil compositesor high-barrier PVdC (Polyvinylidene Chloride) coatings. Thickness typically ranges from 15-50 microns depending on barrier requirements.

常见问题

What is the primary function of the Barrier Core Layer?

To prevent oxygen and moisture transmission through vacuum pouch seals, maintaining product freshness and extending shelf life.

Which materials offer the best barrier properties?

EVOH provides excellent oxygen barrier, while metallized PET or aluminum foil composites offer superior moisture and gas barrier performance.

How does thickness affect barrier performance?

Thicker layers generally provide better barrier properties but increase material cost and may affect sealing characteristics; optimal thickness balances performance with processing requirements.
