Tea bag

Polyethylene, polypropylene, polyvinyl chloride and other plastic containers have the characteristics of generous, beautiful and good packaging and display effect, but their sealing performance is poor. They are mostly used as outer packaging in tea packaging, and they are mostly encapsulated in composite film plastic bags.

Film bag packaging

Plastic composite film has many advantages, such as light weight, not easy to damage, good heat sealing, suitable price and so on. There are many kinds of composite films used for tea packaging, such as moisture-proof cellophane / polyethylene / paper / aluminum foil / polyethylene, biaxially stretched polypropylene / aluminum foil / polyethylene, polyethylene / polyvinylidene chloride / polyethylene, etc. the composite films have excellent gas resistance, moisture resistance, aroma retention, odor resistance, etc. Since most plastic films have 80% ~ 90% light transmittance, in order to reduce the transmittance, ultraviolet suppression can be added to the packaging materials or the light transmittance can be reduced by printing and coloring.

In addition, composite materials based on aluminum foil or vacuum aluminized film can be used for shading packaging. The aluminum foil composite packaging bag is made of metal aluminum. Its metal barrier performance and the practicability of composite plastic film are very strong, which basically meets the aroma preservation requirements of tea.

There are various packaging forms of composite film bags, including three side sealing shape, self-supporting bag shape, folding shape, etc. Packaging because the composite film bag has good printability, using it as sales packaging design has a unique effect on attracting customers and promoting tea sales.
