Shanghai Tangke | High-performance vacuum zipper patch bag

With its high barrier, resealable, moisture-proof and anti-fouling characteristics, patch zipper bags are not only used in the food industry, but also in many fields.Patch zipper bags are mainly used in food packaging and preservation, such as nuts, candy, tea, seafood, frozen ingredients, cheese and other dairy products. 

The advantage of patch zipper bags is that they have high barrier properties: moisture-proof, oxygen-insulation, and flavor preservation, which can prolong the shelf life of food, especially suitable for freezing and preservation.The design of the patch zipper bag can be opened and closed multiple times, making it easy to reseal some ingredients after taking them, ensuring the freshness of the sealed items.

At the same time, patch zipper bags are also used in industrial samples, logistics protection, pharmaceutical and chemical industry and high-end retail. 

Shanghai Tangke New Material Technology Co., Ltd.'s four-layer composite process reconstruction chain bag reliability patent design provides an innovative solution that combines safety and convenience for the food packaging industry. According to the data of the Shanghai Quality Supervision Bureau over the years, the insufficient opening tension of the chain self-sealing bag is the main quality problem - the industry failure rate reached 12%, Some products only reach 60% of the lower limit of the national standard.

The core characteristics of Tangke Brand's patch zipper bag products:
1. Flexible and durable: It is made of high-elasticity composite material, which supports multiple recycling, is not easy to be damaged when filling, and fully adapts to the packaging of items of different volumes.
