Aluminum foil zipper bags are a packaging solution that combines high barrier properties, sealing performance and convenience. They are made of multi-layer composite materials. The front is designed with a transparent window (usually made of PET or transparent PE), which can directly display the contents while retaining the light-blocking and moisture-proof characteristics of aluminum foil. They are widely used in the packaging needs of the food, pharmaceutical, electronic components, cosmetics and other industries.

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.

Suction bag, is a new form of packaging, it combines the design of the self-supporting bag and the suction mouth, mainly composed of two parts of the suction mouth and the self-supporting bag portability: the suction mouth bag can be easily put into the backpack or even the pocket, and can be reduced with the reduction of the contents, more convenient to carry.
Sealing: With good sealing, can effectively avoid light and moisture, extend the shelf life of the product.
Exquisite printing: It has incomparable advantages in the printing performance of traditional beverage packaging, improving product grade and strengthening the visual effect of the shelf.
Versatility: can replace the bottle to use, save costs, improve the competitiveness of products in the market; With suction nozzle, galas chain, can be used repeatedly, strong sealing, easy to save, suitable for manual and automatic filling and sealing.

Coffee bag with air valve is a kind of bag designed for storing coffee beans, with one-way exhaust valve function, can effectively lock the freshness of coffee. ‌

Product characteristics
‌ one-way exhaust valve ‌ : This design makes the gas can only be discharged one-way, can not enter, so as to prevent the coffee beans from moisture and oxidation, maintain its freshness and aroma ‌
‌ eight-side seal design ‌ : The bag adopts the eight-side seal design, which is not only stable, but also can effectively isolate the air to ensure the best preservation of the coffee beans ‌
‌ moisture and anti-oxidation ‌ : The eight-sided sealing bag with air valve can effectively prevent moisture and oxidation and extend the shelf life of coffee beans ‌.

OPP bag is a kind of plastic bag made of polypropylene as raw material, with the following characteristics:
Good sealing: The tightness of the new OPP film is more than twice that of its traditional film, which helps to moisturize and preserve the product2.
Strong anti-counterfeiting: the use of synthetic technology and special printing technology to improve the difficulty of counterfeiting 2.
Environmental protection: The raw materials used in OPP bags are degradable materials, which meet international environmental standards 2.
OPP bags are widely used in jewelry, jade, stationery, toys, tableware, kitchen utensils, clothing and other fields, especially in the outer packaging of commodity sales, which can protect products and improve beauty

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 biggest feature of kraft paper is that it has high tensile strength and breaking strength, flexible and strong, and can withstand greater tension and pressure without breaking. The primary color kraft paper also has better processing properties such as embossing, die-cutting and die-carving. At the same time, it is relatively resistant to water, which makes it useful in some humid environments or scenes where moisture is required

Barrier performance improvement: the composite of matte film, aluminum plating and PE can synthesize the barrier performance of the three. The aluminized layer can effectively block the penetration of light, ultraviolet rays and gases, and the matte film can further enhance this blocking effect, while PE can prevent the penetration of substances such as moisture, thereby extending the shelf life of the packaged item. For example, for some drugs or foods that are sensitive to light and oxygen, this composite film can provide better protection.
Both appearance and practicality: the matte effect brought by the matte film makes the appearance of the package more textured and improves the grade of the product. The metallic luster of the aluminized layer increases the visual appeal of the package, while the utility of PE ensures the flexibility and durability of the package during use. 

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.

Laser film is a new type of coating material, which has the characteristics of ultra-strong abrasion resistance, anti-ultraviolet radiation, anti-pollution and anti-scratch.
Laser film has a wide range of applications, such as Windows, screens, lenses, panels, etc. in automotive, construction, electronics and other fields, as well as the shell of scientific and technological products. In addition, in the field of new technologies such as 5G and smart home, laser film also has a very broad application prospect.

The advantage of degradable plastic bags is that they can be broken down by the natural environment, thereby reducing the long-term impact on the environment.
