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.

Aluminum foil is metal, not plastic. After repeated processing and rolling of aluminum ingots, it is made into 6.5 μ m. 7 μ m. 9 μ m. 12 μ m. 16 μ m. 25 μ m. 40 μ Various thicknesses such as m are commonly used in the soft packaging industry, with a thickness of 6.5 μ m. 7 μ m. 9 μ m. Especially 7 μ M is commonly used, and aluminum foil is mainly used in soft bags for its high barrier properties, which also have some decorative properties

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, three side sealed zipper bags, self standing bags, self standing zipper bags, irregular bags, square bottom bags, organ bags, coffee bags, 25 kg particle bags, heavy packaging bags, VIP board vacuum outer 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.

The puncture resistant aluminum foil bag has a wide range of applications, and can be used in food, biomedicine, electronic products, pesticides, facial mask, construction and other fields.

The bag can be automatically used by the bag packaging machine or manually filled.

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 pure aluminum 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.

真空袋及高温蒸煮袋也基本上都是三边封形式，主要是考虑热封强度、气密性等原因。

三边封袋子还可以做成各种高阻隔袋子，一般高阻隔都是用铝箔作为阻隔层，但考虑到透明度及铝箔易折断，所以有时也会用氧 化铝PET、氧化硅PET、K镀层材料、EVOH材料等高阻隔但同时又是透明的材料来替代铝箔，但这些材料一般采购周期较长，并且价格也比较贵。

三边封袋子使用范围较广，可以用在食品、药品、电子产品、农药、面膜等各个领域。

袋子可以自动给袋式包装机使用，也可以人工灌装使用。
