Stand up pouches & Bags for tea

Stand up zipper pouches for tea is the most tea packaging we have made. Digital printing and gravure printing are the common printing methods. Both methods can satisfy you. The inner layer composite structure can be aluminized film or aluminum foil. The two shading methods have different costs and different effects, and can be customized according to your needs.

At present, more and more tea packaging in the market is packaged in composite film bags. Stand up pouches open window tea packaging bag, you can see the state of the tea more clearly, this packaging bag is also one of our products. There are many kinds of composite films for packaging tea, such as moisture-proof cellophane/polyethylene/paper/aluminum foil/polyethylene, biaxially oriented polypropylene/aluminum foil/polyethylene, polyethylene/polyvinylidene chloride/polyethylene, etc. It has excellent gas barrier properties, moisture resistance, fragrance retention, and anti-peculiar smell. The performance of the composite film with aluminum foil is more superior, such as excellent shading and so on. There are various packaging forms of composite film bags, including three-sided sealing, stand-up bag, and folding. In addition, the composite film bag has good printability, and it will have a unique effect when it is used for sales packaging design.

Tea Packaging Requirements

Moisture resistance

The water content in tea should not exceed 5%, and 3% is the best for long-term storage; otherwise, the ascorbic acid in the tea will be easily decomposed, and the color, aroma and taste of the tea will change, especially at higher temperatures. the rate of deterioration will be accelerated. Therefore, packaging materials with good moisture-proof performance can be selected for moisture-proof packaging, such as composite films based on aluminum foil or aluminum foil evaporated film, which can be highly moisture-proof.

Oxidation resistance

The oxygen content in the package must be controlled below 1%. Too much oxygen will cause some components in the tea to oxidatively deteriorate.

Shading

Since tea contains chlorophyll and other substances, when packaging tea leaves, light must be shielded to prevent the photocatalytic reaction of chlorophyll and other components.

Gas barrier

The aroma of tea leaves is easily lost, and materials with good air-tightness must be used for aroma-preserving packaging.

High temperature

The increase in temperature will speed up the oxidation reaction of tea leaves, and at the same time will cause the surface gloss of tea leaves to fade. Therefore, tea leaves are suitable for storage at low temperatures.
