How does Double PE coated paper cup bottom roll perform in terms of grease, water and moisture resistance?

The performance of Double PE Coated Paper Cup Bottom Roll in the application of the bottom of paper cups is directly related to the overall function of the paper cups and the consumer experience.

Double PE coating has excellent oleophobic properties and can effectively block the penetration of grease. Whether it is cream fat in hot drinks or grease in food packaging, double coating can provide stronger protection to ensure that the bottom of the paper cup will not soften or delaminate due to grease penetration.

The coating thickness in the double PE coating directly determines its grease resistance. The thicker the coating, the stronger its resistance to high-viscosity or high-temperature grease, thereby reducing material degradation caused by long-term contact.

When holding high-temperature beverages, some grease may penetrate ordinary coatings due to thermal effects. Double PE coating has the protection of the upper and lower double layers, so that the bottom of the paper cup can still maintain its ability to block grease even at high temperatures.

The inner and outer double-layer structure of the double PE coating can achieve complete waterproof protection. PE material itself has a very low water absorption rate. After being applied to the bottom roll of the paper cup, it can completely prevent the penetration of liquid and avoid deformation, softening or leakage caused by the bottom being wet.

PE coating is not only waterproof, but also can further enhance the sealing of the bottom of the paper cup through heat sealing process. At the junction of the bottom of the paper cup and the wall, the double PE coating can provide a tighter bonding effect to prevent liquid leakage from the interface.

Double PE coated paper cup bottom rolls usually undergo multiple water resistance tests to ensure that the integrity of the paper cup is maintained after being filled with cold or hot drinks, and there will be no leakage problems even after long-term use.

Double PE coating can not only prevent liquid penetration, but also block water vapor in the air, thereby effectively maintaining the dryness of the paper cup and avoiding the expansion or loss of strength of paper fibers due to moisture absorption.

When serving iced or cold drinks, condensation will form on the surface of the paper cup due to temperature difference. Double PE coating can prevent condensation from penetrating the bottom of the paper cup, ensuring the structural stability of the paper cup and the user experience.

The moisture-proof performance of the double PE coating allows the paper cup to remain unaffected by environmental humidity during storage and transportation, avoiding the problem of paper roll mold or surface peeling.

The thickness, uniformity and stability of the coating process directly affect the performance of grease resistance, water resistance and moisture resistance.

The strength of the paper used in the bottom roll of the paper cup and the adhesion of the coating determine whether the coating can maintain its integrity in complex environments.

The type of liquid (such as greasy, highly acidic or high-sugar drinks) and its temperature will have different degrees of impact on the durability of the double PE coating.

After filling with high-fat liquids, there will be no oil stains or softening on the bottom of the paper cup, proving its excellent barrier performance.

After soaking in water for several hours, there is no leakage or coating peeling at the bottom of the paper cup, indicating that it has excellent water resistance.

After being stored in a high-humidity environment for several days, the bottom of the paper cup remains dry and structurally intact, with excellent moisture resistance.

Double PE Coated Paper Cup Bottom Roll has excellent performance in grease resistance, water resistance and moisture resistance, and can effectively cope with different beverage and environmental requirements. By selecting high-quality coating materials and advanced production processes, the double PE coated paper cup bottom roll ensures that the paper cup remains structurally stable during use and provides a reliable user experience.
