Printing: Within 12 colors (benzene and ketone free environmentally friendly ink), customized by customers

Materials: Generally composed of polyester film (PET), aluminum foil (AL), aluminized polyester film (VMPET), nylon (PA or NY), polyethylene film (PE), polypropylene film (CPP) and other materials, such as PET/AL/PE, PET/AL/NY/PE, PET/AL/NY/CPP, OPP/AL/PE, BOPA/VMPET/PE, PET-AL2O3/PA/RCPP, etc.

Features: It has the characteristics of avoiding light, high resistance to oxygen and humidity, multiple opening and closing of the zipper, high strength composite fastness, and difficulty in peeling and delamination. By adjusting the thickness and formula of the barrier layer material, it can also achieve the high barrier effect of oxygen and moisture permeability required by customers.

Common bag types: three side sealed bags, two side sealed bags, three side sealed self standing bags, back sealed bags, eight side sealed bags, etc. We customize various sizes of packaging bag products according to customer requirements.

Enhanced packaging function: It can also be equipped with zippers, coffee valves, one-way exhaust valves, etc., to meet more additional requirements.

It can be used to package infant food, Pet food, medicine, snack food, coffee, storage bags, refrigerator food collection, milk preservation, liquid packaging, etc.

Printing: Zippered self standing bags can be printed in up to 12 colors, or they can be made into transparent or natural colors such as aluminum foil without printing.

Bag making: The bag making of zipper self-supporting bags mainly focuses on the sealing fastness of the zipper and bag body, as well as whether the ultrasonic heating at both ends of the zipper is sufficient, otherwise air leakage may occur.

The high composite strength zipper self-supporting bag is designed for the preservation of the contents, making it easy to open, retrieve, and store. If double zippers are used, it can also be used to store liquid items and vacuum.

However, zipper self-supporting bags are prone to leakage and zipper detachment, as well as air leakage at the zipper end.

Considering that the zippers are all low-temperature heat sealed, the self standing zipper bag cannot be used for boiling or high-temperature steaming, otherwise the zipper will deform or even melt and cannot be used again.

真空袋及高溫蒸煮袋也基本上都是三邊封形式，主要是考慮熱封強(qiáng)度、氣密性等原因。

三邊封袋子還可以做成各種高阻隔袋子，一般高阻隔都是用鋁箔作為阻隔層，但考慮到透明度及鋁箔易折斷，所以有時(shí)也會(huì)用氧 化鋁PET、氧化硅PET、K鍍層材料、EVOH材料等高阻隔但同時(shí)又是透明的材料來替代鋁箔，但這些材料一般采購(gòu)周期較長(zhǎng)，并且價(jià)格也比較貴。

三邊封袋子使用范圍較廣，可以用在食品、藥品、電子產(chǎn)品、農(nóng)藥、面膜等各個(gè)領(lǐng)域。

袋子可以自動(dòng)給袋式包裝機(jī)使用，也可以人工灌裝使用。
