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.

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

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. 

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

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.

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.
 

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

Beautiful packaging, clear printing, PET material is environmentally friendly, non-toxic, safe, good heat resistance, used for storing rice and other food

• ‌OPP bag ‌ : The main material is ‌ Polypropylene, especially Oriented Polypropylene, which has excellent transparency and gloss.
•  
• ‌OPP bag ‌ : with high transparency, good moisture and dust resistance, as well as anti-static properties, so that the goods can be kept clean and dry after packaging.
•  
• OPP bag ‌: due to its high transparency and good display effect, it is often used in occasions where goods need to be clearly displayed, such as food packaging, clothing packaging, stationery packaging, etc., and it is also widely used in fields where the quality of goods needs to be protected.
