III. Waterproof performance of food grade PE coated paper cups

A. The waterproof principle of PE coating

The waterproof performance of food grade PE coated paper cups is determined by the characteristics of the PE coating. PE, also known as polyethylene, is a material with excellent water resistance. PE coating forms a continuous waterproof layer on the surface of the paper cup. It can effectively prevent liquid from entering the inside of the paper cup. PE coating has good adhesiveness and plasticity through its polymer structure. It can tightly bond with the surface of the paper cup to form a layer of coverage, thereby achieving a waterproof effect.

B. Waterproof performance testing and certification agency

The waterproof performance of food grade PE coated paper cups usually requires a series of tests and certifications to verify their compliance. A commonly used testing method is the Water Drop Penetration Test. This method refers to dropping a certain amount of water droplets onto the surface of a paper cup. Afterwards, observe whether the water droplets penetrate into the inside of the paper cup for a certain period of time. Evaluate the waterproof performance through this method. In addition, other testing methods can also be used. Such as wet friction test, liquid pressure test, etc.

There are multiple certification bodies for the waterproof performance of paper cups internationally. For example, FDA certification, European Union (EU) certification, China General Administration for Quality Supervision, Inspection and Quarantine (AQSIQ) certification, etc. These institutions will strictly supervise and audit the materials, processing technology, waterproof performance, etc. of paper cups. And this helps ensure that the paper cups comply with corresponding national standards and regulations.

C. Leakage resistance of PE coated paper cups

Food grade PE coated paper cups have good leak resistance. PE coating has high sealing and adhesion properties. It can effectively prevent liquid from leaking out around the paper cup. Paper cup containers require the selection of appropriate manufacturing processes and materials. Only in this way can the PE coating form a tight bond with the surface of the paper cup. Afterwards, it can form an effective sealing barrier. And this can prevent liquid from leaking from the seams or bottom of the paper cup.

In addition, paper cups are usually equipped with a leak proof design. Such as sealing caps, sliding caps, etc. These further enhance the anti leakage performance of the paper cup. These designs can reduce liquid spillage from the opening on the top of the paper cup. At the same time, these can also avoid side leakage of the paper cup.

D. Moisture and juice impermeability

In addition to waterproof performance, food grade PE coated paper cups also have excellent moisture and juice resistance. PE coating can effectively prevent liquid substances such as moisture, moisture, and juice from penetrating into the inside of the paper cup. PE coating forms a barrier layer through its polymer structure. It can prevent liquid from passing through the gaps inside the paper material and paper cup.

Due to the fact that paper cups are usually used to hold liquids such as hot or cold drinks. The anti permeability performance of PE coating is very important. It can ensure that the paper cup will not become soft, deformed, or lose structural integrity due to the penetration of moisture and juice during use. And he can also ensure the stability and safety of the paper cup.

IV. The application of food grade PE coated paper cups in the coffee industry
