The outer VMPET film of the aluminized Yin and Yang bag is a flexible packaging material formed by plating an extremely thin layer of metal aluminum on the surface of the plastic film with a special process. The inner layer is a heat-sealable CPE or CPP, which has anti-static, light insulation, oxygen insulation and other properties, and is the preferred alternative product of the aluminum foil bag

Made of high-quality food-grade thick plastic, tough and light, smooth edges, will not scratch you, and can be reused and easy to use.

Food aluminum foil packaging bag has the following benefits:

Excellent barrier properties: aluminum foil packaging bags have excellent barrier properties, which can effectively isolate the invasion of external factors such as oxygen, moisture, and bacteria, and maintain the freshness and quality of food. Especially for easily oxidized foods, such as coffee, chocolate, etc., aluminum foil packaging bags can extend its shelf life .
 

The outer material is usually pure pulp kraft paper, kraft paper can be divided into white kraft paper and yellow kraft paper. Part of the window kraft paper outer layer will be double subfilm, which makes it waterproof, for example, in some frosted window kraft paper products have this design.
In order to moisture-proof, the inner layer is often coated, like the kraft paper products with transparent Windows, and the inner layer of the coating can play a good moisture-proof effect

Non-toxic and tasteless: pure aluminum packaging bag, non-toxic and tasteless. Frozen, dark, good sealing, not easy to split air leakage, play a very good anti-purification, extended shelf life and other infections.

Wide range of application: pure aluminum packaging bags especially in tea, coffee packaging has a very high advantage. The reverse ability is strong and the isolation function is good, airtight and water vapor. Multi high temperature compliance. At high temperature or high temperature, the character is stable, the light shielding is strong, and the box is excellent.

Protect food quality: The excellent barrier properties of aluminum foil packaging bags can effectively protect food from external factors, extend the shelf life of food, and ensure the freshness and quality of food.

Enhance product Image: Aluminum foil packaging bags can be printed and designed to achieve personalized and exquisite packaging, and enhance product image and market competitiveness.

The suction nozzle of the self-supporting bag is usually made of plastic and is specially designed so that it can be tightly attached to the packaging bag. The design of the nozzle effectively prevents liquid leakage while allowing consumers to control the flow during use. In addition, the suction nozzle can also conveniently close the bag to avoid air entry, thereby extending the shelf life of the contents of the package

Kraft paper bags have the advantages of environmental protection, strength and durability, waterproofness, recyclability, printing performance, processing performance, shading and heat insulation and personalized embodiment.
 

Environmental protection: Kraft paper bags non-toxic, tasteless, non-polluting, in line with national environmental standards. It has the characteristics of high strength and high environmental protection, and is one of the most popular environmental protection packaging materials in the world.

Strength and durability: Kraft paper bags have high strength and durability, and can withstand greater tension and pressure. This makes it an ideal choice for packaging materials that can protect items from damage.

Waterproof: The Kraft paper bag has a certain degree of waterproofness and can prevent moisture penetration to a certain extent. This makes it advantageous for outdoor use or in environments that require protection from moisture.

VMPET:1. Strong air barrier performance, anti-oxidation, waterproof and moisture-proof
2. Strong mechanical properties, high anti-blasting performance, anti-puncture and anti-tear performance.
3. High temperature resistance (121), low temperature resistance (-50), oil resistance, good fragrance performance.
4. Non-toxic and tasteless, in line with food, drug packaging hygiene standards.
5. Good heat sealing performance, flexibility, high barrier performance.

Aluminum foil food bags have good performance in blocking oxygen and water, which can prevent the virus and microorganism caused by food oxidation from breeding, thus the phenomenon of food mildew. In the packaging of cooked food products, the use of aluminum foil food bag vacuum technology for food processing.

The surface of the aluminum foil is extremely clean and hygienic, and no bacteria or microorganisms can grow on its surface.
1.Aluminum foil is a non-toxic packaging material, it can be in direct contact with food without any danger to human health.
2.Aluminum foil is a tasteless and odorless packaging material, which will not make the packaged food have any peculiar smell.
3.Aluminum foil itself is not volatile, it itself and packaged food will never dry or shrink.
4.No matter at high temperature or low temperature, the aluminum foil will not have the phenomenon of grease penetration.
5.Aluminum foil is an opaque packaging material, so it is a good packaging material for products exposed to sunlight, such as margarine.
6.Aluminum foil has good plasticity, so it can be used for packaging products of various shapes. Can also be arbitrarily caused by various shapes of containers
