Publish Time: 2024-10-16
The MOPP coating applied on Kraft Paper Bags has a variety of specific functions, mainly focusing on protection and functionality.
1. Waterproof and moisture-proof
The MOPP coating significantly improves the waterproof performance of Kraft Paper Bags. This coating can effectively block the penetration of moisture and prevent the paper bag from deforming or being damaged due to moisture absorption. This is especially important for items that need to be stored and transported in humid environments, such as food, medicines and industrial raw materials.
2. Enhanced strength
The MOPP coating increases the mechanical strength of the Kraft Paper Bag, making it more durable. This coating forms a tough protective film on the surface of the paper that can resist tearing and abrasion. Therefore, the MOPP-coated Kraft Paper Bag is more suitable for contact with sharp objects or heavy pressure during transportation.
3. Barrier to gas and odor
The MOPP coating has good gas barrier properties, which can prevent gases such as oxygen and carbon dioxide from passing through the paper bag. This is crucial for sensitive products that need to be stored for a long time, such as fresh food, medicines and electronic components. At the same time, this coating can effectively block external odors and maintain the original smell of the items in the bag.
4. Anti-ultraviolet
Some types of MOPP coatings have anti-ultraviolet function, which can protect the items in the bag from damage by ultraviolet radiation. This is especially important for medicines and certain chemicals that need to be stored for a long time, because ultraviolet rays may cause photochemical reactions and reduce the quality of the product.
5. Anti-static
In some specific application scenarios, MOPP coatings also have anti-static functions. This coating can reduce or eliminate static electricity accumulation and is suitable for handling flammable, explosive or static-sensitive items such as electronic components and chemical products.
6. Aesthetics and brand display
MOPP coatings can improve the gloss and smoothness of Kraft Paper Bags, making the bags look more beautiful. This is very beneficial for retail and brand display purposes, because beautiful packaging can enhance the brand image and attract customer attention.
7. Environmental protection
Although MOPP coating itself is a synthetic material, in some applications, degradable bio-based MOPP coatings can be selected. This coating not only has the above functional characteristics, but also can be naturally decomposed under appropriate conditions to reduce the impact on the environment.
Overall, the application of MOPP coating in Kraft Paper Bag not only enhances the physical properties and durability of paper bags, but also gives them multiple functions such as moisture-proof, waterproof, gas-proof, UV-proof and anti-static. These characteristics make MOPP-coated Kraft Paper Bag more widely used in various industrial and commercial applications.
