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

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

Features: It has the characteristics of avoiding light, high oxygen resistance, and high humidity resistance. Adjust the thickness and formula of the barrier layer material to 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.

For content packaging that requires an extended shelf life, UV protection, anti-static, vacuum extraction, and printing aesthetics, aluminum foil material will be considered as the middle high resistance barrier layer. It is generally mainly used in fields such as food, medicine, pesticides, electronic products, and biomedicine.

Printing: Except for the blister packaging on the medicine package, it will be directly printed on aluminum foil, and most composite packaging films will not be directly printed on aluminum foil.

Composite: The main consideration of aluminum foil composite is the tunnel and crease of the finished roll film due to poor tension control and mismatch of the materials themselves, which makes it impossible for customers to use. Especially in cosmetics industry such as facial mask, the requirements for appearance are almost strict, and no crease is allowed after composite.

In addition, due to the characteristics of aluminum foil processing, sometimes aluminum foil is not properly treated and contains oil stains, which affects the composite fastness and leads to delamination.

Composite also needs to consider the bright or dark side orientation of the aluminum foil, which affects the aesthetics of the product. In most cases, the dark side of the aluminum foil faces outward, and the composite product will have a matte effect.

Bag making: The main consideration for making aluminum plated bags is not to break the aluminum foil, which can lead to its barrier properties.

Aluminum foil is a relatively cheap and easy to purchase high barrier material. It can conduct electricity, make Antistatic bag, play the role of electrostatic shielding, and prevent ultraviolet rays and light. But because it is metal, it is easy to break, leading to a decrease in local insulation. At the same time, the thermal conductivity is high, and the vacuum insulation effect is not very ideal. Due to its opacity, it is not possible to meet the customer's requirements for both high barrier and transparency of the product. Therefore, aluminum oxide PET, silicon oxide PET, PVDC film, and EVOH film can only be used as substitutes.

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，所以有時也會用氧 化鋁PET、氧化硅PET、K鍍層材料、EVOH材料等高阻隔但同時又是透明的材料來替代鋁箔，但這些材料一般采購周期較長，并且價格也比較貴。

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、面膜等各個領域。

袋子可以自動給袋式包裝機使用，也可以人工灌裝使用。
