Q1: What are the direct raw materials for producing disposable environmentally friendly paper tableware?
A1: The paper that has been coated is called "coated paper".
Q2: What is the sequence for printing disposable environmentally friendly paper tableware?
A2: Some processes choose to print before the paper is coated (inner printing), while others print after the paper is coated (surface printing). It is usually more common to print paper after lamination, as the surface of PE film is smooth and the printing effect is better.
Q3: How many steps are there in the core process of molding disposable environmentally friendly paper tableware?
A3: The production of disposable environmentally friendly paper tableware involves four steps: feeding, heating, stamping, and trimming.
Feeding: The printed laminated paper roll is fed into the compression molding machine. The machine will first cut the paper roll into rectangular pieces of a specific size.
Heating: The sheet material is transported to a heating station for preheating, which slightly softens the PE coating layer, increases plasticity, and facilitates molding.
Stamping forming: The preheated sheet material is fed into a mold with a specific tableware shape (such as cup or bowl). The mold is divided into an upper mold (male mold) and a lower mold (female mold). Under high pressure, the upper mold is pressed downwards to squeeze the sheet material into the lower mold, causing it to instantly form.
Edge cutting: During the stamping process, the sharp edges of the mold will cut off excess scraps. These scraps will be collected and recycled into pulp for reuse.
