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. 

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.

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.

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.
