The paper cup blanks factory introduces the quality requirements of the best paper cup raw material roll from China

In addition to the general processing performance requirements, the best paper cup raw material roll from China also has some other special requirements. The requirements for high standards and high quality mainly include the following aspects.
1. High wet strength, high stiffness (or thickness) and high sizing. In order to make the best paper cup raw material roll have a high degree of sizing to meet the requirements of use, it is necessary to use rosin glue and AKD glue for sizing at the same time.

Rosin gum can provide resistance to hot hydrogen peroxide but cannot resist the penetration of lactic acid in dairy products from the edge portion into the cardboard. AKD sizing agent can provide the permeation resistance of the best paper cup raw material roll from China to the liquid being packaged but cannot effectively provide the resistance to hot hydrogen peroxide. Therefore, using rosin gum and AKD sizing at the same time can make full use of the characteristics of these two sizing agents, and endow the paper cup raw material roll with stronger resistance to edge penetration.
2. Good processing performance.
3. It has the ability to resist edge penetration (this is due to the exposed paper edges on the cup body and cup bottom of the best paper cup raw material roll coated original).
4. It has the ability to resist condensed water (condensed water will be generated on the outside of the coated paper when one-sided coated or one-sided waxed coated paper is filled with cold liquid).
5. It has the ability to resist the penetration of the paper surface (when the coating film of the best paper cup raw material roll from China leaks, it can resist the penetration of liquid).
