Tea bag

Polyethylene, polypropylene, polyvinyl chloride and other plastic containers have the characteristics of generosity, beauty and good packaging and display effect, but their sealing performance is poor. They are mostly used as external packaging in tea packaging, and their packaging is mostly sealed with 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, and is widely used in packaging. 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, fragrance retention, odor resistance, etc. Since most plastic films have a light transmittance of 80% - 90%, 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 aluminum coating can be used for shading packaging. The aluminum foil composite packaging bag is pressed with metal aluminum, and its metal barrier performance composite plastic film is very practical, which basically meets the aroma preservation requirements of tea.

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