Paper cup paper is extruded from paper base paper and plastic resin particles. PE resin is generally used for plastic resin. After the paper cup base paper is coated with a single-sided PE film or a double-sided PE film, it becomes a single PE paper cup paper or a double PE paper cup paper. PE itself is non-toxic, odorless, tasteless, reliable in hygienic performance, stable in chemical properties, balanced in physical and mechanical properties, good in cold resistance, resistant to water, moisture and certain oxygen barrier, good oil resistance, good molding performance and heat. Good sealing performance and so on. PE production of large film, convenient source, low price, but not suitable for high temperature cooking, if the paper has special performance requirements, the resin should have the corresponding performance when coating.

Generally, at the time of purchase, the paper cup is mainly determined by observing the appearance characteristics, and the good paper cup generally performs the following test quality inspection: 1. Functional test: Test whether the paper cup can hold liquid, such as water. 2. Performance test: Test whether the paper of the paper cup is thick enough and not easy to be deformed. 3. Stress test (load test): Whether the liquid full of paper cups will be bad 4. Recoverability test: After the liquid is poured out, the paper cup can be restored to the original 5. Strength test: Whether the paper cup will soften and damage after a period of liquid. 6. Appearance test: Whether the shape of the paper cup is beautiful, the pattern is beautiful 7.

Processing form Paper cup paper can be processed into a conical or cylindrical cup type, and can also be processed into other shapes of ice cream cup mechanism/tissue for daily use, so the paper cup is gradually becoming popular. Paper cups can be roughly divided into cold drink cups and hot drink cups according to their use. The quality requirements for paper cup materials vary depending on the application and the type of processing. In addition to meeting the requirements of packaging processing performance, paper cup materials must also have certain printability, and paper cup printing should also meet the conditions of heat sealing in paper cup processing. Hot drink cup It is usually used for the hot beverage packaging trade. The processing material is paper with single-sided PE composite, that is, single-sided coated paper. Generally, printing is performed on a non-PE surface and printed directly on the paper. Due to the needs of hot drinks, such paper cups need to have cer...
