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.

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.

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 ‌.

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 .
 

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. 

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.

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.

As a common tea packaging material, aluminum foil bag has good moisturizing performance: aluminum foil bag can effectively block air and moisture, reduce the contact between tea and the external environment, so as to maintain the humidity and newness of tea. The aluminum foil bag can prevent the tea from being too dry or damp, and keep the taste and aroma of the tea.
Good protection effect: Aluminum foil bag has excellent anti-oxidation and sealing performance, which can effectively prevent air, light and moisture from entering the package, thereby extending the shelf life of tea. Aluminum foil bags can prevent tea from being exposed to light, reduce the possibility of oxidation of photosensitive substances in tea, and maintain the color and taste of tea.

The special-shaped bag breaks through the shackles of the traditional square bag, turns the straight edge of the bag into a curved edge, thus reflecting different design styles, and has the characteristics of novelty, simplicity, clarity, good identification, and highlighting the brand image.
The emergence of special-shaped bags is of great significance to the expansion of packaging design forms. Designers can freely play when designing special-shaped bags, so that more design dreams can come true. For example, the shape of the packaging bag of various fruit slices (pineapple slices, etc.) is designed into the corresponding fruit shape (pineapple shape, etc.), and after the soft packaging bag is made and the fruit slices are packaged, excellent packaging display and promotion effect can be achieved.

High strength: it can withstand a certain external force, and it is not easy to be damaged during transportation and storage.
The extension performance is good, the deformation modulus is large: it can adapt to a certain degree of stretching and deformation without breaking.
Acid and alkali resistance, corrosion resistance: suitable for packaging a variety of products with different chemical properties.
Aging resistance: It is not easy to deteriorate during long-term storage or use, so as to ensure the effectiveness of the packaging.
Good anti-seepage performance: effectively prevent the packaged products from leaking or being invaded by external substances.
