Paper cups have become an integral part of our daily lives and are widely used all over the world. Paper cups can be seen everywhere, whether it is in the catering industry or in living places such as companies or families.
The main raw material used in the production of paper cups is PE coated paper. PE stands for polyethylene, a thermoplastic polymer that provides the cup with a waterproof layer. This layer ensures that the cup stays strong and leak-proof, allowing you to enjoy your drink worry-free.
GSM ( or grams per square meter ) is the unit of measurement used to determine the weight and thickness of paper. The higher the GSM, the thicker and more durable the paper. For paper cups, GSM in the range of 170 to 350 is commonly used. This collection ensures that the cups are the perfect balance between sturdiness and flexibility, making them easy to hold and preventing any leakage.
But why does GSM range matter for paper cups? The main goal, then, is to ensure that the cup can hold the weight of the drink and not deform or collapse due to moisture. The higher GSM provides the mug with the necessary strength and rigidity, ensuring it can hold hot liquids without issue. On the other hand, a lower GSM may make the cup too flimsy and prone to leaks.
The process of PE-coating the paper jumbo rolls used for the production of paper cups. The process involves coating the paper with a layer of polyethylene to enhance its waterproof and insulating properties. The PE coating prevents moisture from penetrating the paper and maintains the ideal temperature for beverages, keeping them hot or cold for longer.
It is very important that the PE coating is applied evenly on the paper surface. This ensures that the cup remains leak-proof and avoids any unwanted spills. The thickness of the PE coating is usually 10 to 20 microns, depending on the desired quality and function of the cup. This PE-coated paper is usually called “single-sided PE coated paper” or “double-sided PE coated paper”, depending on where the coating is applied.
In addition to GSM and PE coating, other factors also affect the overall quality and function of paper cups. The quality of paper cup raw materials, manufacturing process and design of paper cup fan play an indispensable role. PaperJoy has been producing PE coated paper roll, paper cup fan and other paper cup raw materials for 17 years, and provides free samples so that you can better experience the perfect effect of the product.
