Corrugated paper cups represent the emergence of new technologies and processes, driving continuous improvements in paper cup manufacturing techniques.

Corrugated paper cups represent the emergence of new technologies and processes, driving continuous improvements in paper cup manufacturing techniques. New types of paper cups will emerge, further promoting and enhancing the variety and appeal of products. The surface of cold drink paper cups must undergo wax spraying or wax immersion treatment. This is because cold beverages can cause water to accumulate on the surface of the paper cup, leading to softening. Applying wax provides waterproofing. At temperatures between 0°C and 5°C, this wax remains highly stable and safe.

Custom-made corrugated paper cups require enhanced insulation and compression strength. To achieve this, the insulation capacity of the outer cup body must be strengthened. As long as the corrugation marks are not visible after the face paper is glued, lighter-weight paper can be used; the core paper and corrugated paper should preferably be made of grass pulp or wood pulp paper with good stiffness and high ring compression strength. Avoid using medium-strength or standard-strength corrugated paper, as these are often blends of virgin and recycled pulp, which absorb water quickly, have low ring crush strength, and while they may have good flexibility, they lack rigidity.

However, if used for hot beverages, once the beverage temperature exceeds 62°C, the wax melts, causing the paper cup to absorb water and deform. The melted wax contains high levels of impurities, particularly polycyclic aromatic hydrocarbons (PAHs), which are potential carcinogens that can harm human health when ingested with the beverage. The surface of hot beverage paper cups is coated with a layer of nationally approved special polyethylene film, which not only has excellent heat resistance but is also non-toxic even when immersed in high-temperature beverages. The above is an introduction to Shenzhen Taimeile, a custom corrugated paper cup manufacturer, brought to you by our editor.
