Free Coated Paper Rolls for Coffee and Beverage Model Number Non Plastic Coated Paper

Here is the production process of plastic - free coating lamination on paper cup paper:

Raw Material Preparation

● Select suitable plastic - free coating materials, such as polylactic acid (PLA), starch - based resins, or other biodegradable polymers. These materials should meet food - contact safety standards.

● Prepare high - quality base paper for paper cups, which should have appropriate strength, smoothness, and porosity.

Coating Solution Preparation

● Dissolve or disperse the plastic - free coating material in a suitable solvent or carrier liquid. Add necessary additives, such as surfactants, cross - linking agents, and antioxidants, to improve the performance of the coating solution.

● Stir and mix the coating solution evenly to ensure a uniform composition and viscosity.

Coating Application

● Use a coating machine, such as a gravure coater, slot - die coater, or roll coater, to apply the coating solution onto the surface of the base paper. The coating machine can precisely control the amount and uniformity of the coating.

● Adjust the coating process parameters, such as coating speed, pressure, and temperature, according to the characteristics of the coating material and the requirements of the paper cup.

Drying and Curing

● Pass the coated paper through a drying tunnel or oven to evaporate the solvent in the coating solution and cure the coating. The drying temperature and time should be carefully controlled to ensure the complete curing of the coating without affecting the quality of the paper.

● Some plastic - free coatings may require additional curing processes, such as ultraviolet (UV) curing or heat - activated cross - linking, to improve the final properties of the coating.

Quality Inspection

● Check the thickness, uniformity, and adhesion of the coating to ensure that it meets the specified quality standards. Use instruments such as micrometers and adhesion testers for measurement and testing.

● Inspect the physical and chemical properties of the coated paper, including water resistance, oil resistance, and strength, to ensure that the paper cup can meet the requirements of normal use.

Finishing and Packaging

● Roll the coated paper into reels for easy handling and transportation. Cut the reels into appropriate lengths and widths according to the size requirements of paper cups.

● Package the finished coated paper in a clean and dry environment to prevent contamination and damage before it is sent to the paper cup manufacturing process.

Under the demands of the market and the overall environment, plastic-free coating lamination(non-plastic coating) has gradually replaced PE lamination as an environmentally friendly and degradable material.

● Catering industry: Disposable paper cups (for cold and hot drinks), noodle bowls, soup buckets.

● Takeout packaging: oil-splashed noodle boxes, fried chicken boxes, French fries cups, salad bowls.

● Food retail: baking packaging, fresh food trays, outer packaging for frozen foods.
