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.

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. 

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.

Frosted zipper bags are usually made of special PE or CPE materials that have good weather resistance, ozone resistance, aging resistance, chemical resistance, and flame retardation. They are not prone to explosive edges, folds, deformation, and can effectively prevent the product and the bag friction caused by scratching the surface. The flexibility of the frosted zipper bag is good, the feel is silky and soft, suitable for packaging valuable and fragile items, and effectively protect the goods from the damage of external factors

The frosted zipper bag has a unique frosted texture, and the surface shows a delicate frosted effect, giving people a high-grade feeling. This texture not only improves the packaging grade of the product, but also increases the shopping experience.

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

Commonly used in the production of PE zipper bag, PE stick bone bag, PE clip chain bag, etc., has good load-bearing performance and insulation performance, clear printing pattern, acid and alkali resistance, not easy to dissolve in organic solvents ‌

• ‌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.

The usefulness of aluminum foil bags

As the name suggests, aluminum foil bags are not plastic bags, and may even be better than regular plastic bags. When you need to refrigerate or pack your food now, and you want to keep the food fresh for the longest possible time, which packaging bag should you choose? Don’t worry about which bag to choose, aluminum foil bags are the best choice.

Today we talk about the classification of aluminum foil bags:

Because the raw materials contain aluminum foil, aluminum foil bags and aluminized bags are often confused. Aluminum foil bags have many classifications, names, and characteristics, which make it difficult to distinguish them. Today we will sort them out:

There are generally five types of aluminum foil bags according to the material:

Yin-yang bag: one side is a transparent composite material, the other side is aluminized material, the appearance is silver-white, and the surface is brightaluminum foil bag
