The four-layer composite film of PET/AL/PA/CPP combines four materials with distinct properties through precise technology, creating an all-round high-barrier packaging material. 
The outer layer (PET) provides excellent mechanical strength and wear resistance. It has a high surface gloss and is easy to print, allowing for the customization of various patterns to enhance brand image. Additionally, it offers excellent dimensional stability and abrasion resistance, protecting packaged goods from scratches during distribution.
The barrier layer (AL) offers 100% light, oxygen, and water vapor barrier, effectively preventing product oxidation and moisture absorption. 
The reinforcing layer (PA) provides outstanding puncture, impact, and tear resistance, ensuring that the package is less prone to damage during use and is more durable, with high applicability for packaging different products. Additionally, PA also exhibits good gas barrier properties.
The inner layer (CPP) has excellent heat-sealing performance. Compared to ordinary PE, the seal of CPP film is more secure.
It is applicable in a wider range of fields. Common application areas include packaging of precision instruments, chemical reagents, etc., where there is a high demand for moisture and oxidation resistance.

AL/PET/AL triplex film with a symmetric three-layer structure—featuring two aluminum foil (AL) layers sandwiching a polyethylene terephthalate (PET) core. 
The dual AL layers form the film’s core barrier, delivering ultra-high resistance to oxygen, moisture, water vapor, gases, and all light (including UV).It also offers good heat resistance and boosts the film’s rigidity, fitting processes like heat sealing or lamination.
PET film as the structural backbone between the two AL layers, PET provides strong mechanical strength, high tensile resistance, and excellent dimensional stability—preventing AL layers from wrinkling, tearing, or deforming during processing, transport, or storage.
DINGHE allows customization of each layer thickness and product width to suit cable shielding materials, the production of aluminum foil flexible ducts, and high-grade industrial packaging.

PET/AL/PE Triplex Film is a high-performance composite packaging material engineered with a three-layer laminated structure, integrating the unique advantages of each component to deliver exceptional functionality for diverse industrial and packaging applications.
The PET outer layer as the outermost protective layer, PET boasts excellent mechanical strength, high tensile resistance, and superior dimensional stability. and external impacts, while also providing good transparency and printability.
The aluminum foil core acts as a barrier with unmatched performance. It completely blocks light (especially UV rays), oxygen, moisture, and gases, preventing product oxidation, moisture absorption, and deterioration.
The innermost polyethylene layer has excellent heat sealing properties. PE is a commonly used heat-sealing material with a relatively low melting point. It can be melted through heating and firmly bonded to itself or other PE layers to form sealed packaging. It is non-toxic, odorless, and possesses excellent chemical resistance, ensuring it does not react with the contents. This makes the film more convenient to use, eliminating the need to apply glue again. It ensures a convenient and reliable sealing effect during the packaging process.
DINGHE also allows for customization of the thickness of each layer structure, the color of the film, and its width. Meet the different needs of customers

Based on this, to meet higher requirements (such as high-temperature sterilization, high barrier properties), other functional layers will be introduced to form a multi-layer structure, for example:

‌PET/AL/PE‌: An aluminum foil (AL) layer is added in the middle, which significantly enhances the ability to block oxygen, light and water vapor, and is suitable for packaging of medicines and high-temperature sterilized foods.‌

‌PET/VMPET/PE‌: Aluminized PET (VMPET) is used instead of the aluminum foil, maintaining good barrier properties while making the material more flexible and possibly lower in cost. It is often used in scenarios where barrier properties are required but not extremely high.‌

PET/NY/PE‌: Nylon (NY) film is added, further enhancing the puncture resistance and toughness of the material, suitable for packaging contents with sharp edges or hardness.‌
