We recently received a inquiry through our official website from a Turkish customer who needs an 84mm structure PE-AL-PE. The packaging used for liquid shampoo. Compared with the traditional single layer of polyester film material for package,the packaging bag made of aluminum PE film is less easy to break during packaging and transportation, and can effectively avoid light, avoid any physical or chemical changes caused by light. For the materials of this structure, we are very excited and confident to share, which is one of the materials that we are best at and conventional structure. We can recommend PE-AL-PE of different thickness and color according to different customers, which can meet the needs of different customers
PET-AL-PE is a composite material commonly used in packaging for liquid products such as shampoo. It consists of three layers of different functional materials, each with its own unique advantages, which together provide superior protective performance and practicality for packaging.
Composition and function of PET-AL-PE structure
PET layer (polyethylene terephthalate) :
Function: As an outer layer, PET has high strength and wear resistance, while providing good print ability, which can achieve high-quality printing results and enhance the visual appeal of the packaging. PET also has certain barrier properties, preventing the penetration of oxygen and water.
Characteristics: It has good mechanical strength, impact resistance and heat resistance, and can resist physical damage that may be encountered during transportation and storage.
AL layer (aluminum foil) :
Function: The aluminum foil layer is the middle layer, which mainly provides excellent barrier performance to prevent light, oxygen and moisture from entering the packaging bag. This layer acts as a shield to ensure that the ingredients of the shampoo are not oxidized, extending the shelf life of the product.
Characteristics: Aluminum foil has good barrier property, almost completely opaque to light and gas, prevent the contents from contact with the external environment, so as to maintain the freshness and stability of the product.
PE layer (polyethylene) :
Function: As the inner layer, the PE layer is directly in contact with the shampoo, providing good heat sealing performance, ensuring the sealing of the package and preventing the leakage of the contents. PE has a good tolerance to most chemicals, so it can safely store shampoos of various ingredients.
Characteristics: PE is flexible and durable, suitable for contact with liquid products, while having low permeability and protecting the contents from external contamination.
The advantages of PET-AL-PE as a shampoo bag
Excellent barrier performance: the aluminum foil layer effectively blocks oxygen, moisture and light, preventing the deterioration of the composition of the shampoo and ensuring its quality and stability.
Good mechanical properties: The PET layer provides the strength and durability of the packaging bag, can withstand a certain amount of extrusion and stretching, reducing the risk of damage during transportation and storage.
Safety and compatibility: As the inner layer, the PE layer is safe and non-toxic, and is compatible with the ingredients of the shampoo, and will not undergo chemical reactions to ensure the purity of the product.
Heat sealability: The PE layer enables the packaging bag to achieve a reliable seal through heat sealing, preventing leakage and contamination.
Visual appeal: The high transparency and good printing effect of the PET layer enable the packaging to clearly display brand and product information and enhance market competitiveness.
Application scenario
PET-AL-PE composites are ideal for packaging liquid products such as shampoos, conditioners and body washes, especially where long periods of storage and transportation are required. It can not only effectively protect the quality of the product, but also improve the market performance of the product through excellent packaging design.
