Customized Width 860mm PLA Coated Paper Cup Rolls for Paper Cup

The production process of PLA-laminated paper cups mainly includes these steps:

1. Raw paper preparation: Select food-grade paper pulp (usually wood pulp) with sufficient stiffness and strength for cup shaping.

2. PLA lamination: Feed the paper into a laminator to evenly coat a layer of molten PLA, which cools and solidifies to form a waterproof, oil-resistant film.

3. Cup forming:

● Cut the laminated paper into fan-shaped sheets.

● Roll into a cup cylinder and seal edges (via heat or adhesive).

● Bond a circular bottom to the cylinder for leak-proof sealing.

4. Surface treatment: Print food-grade ink patterns/logos for aesthetics and branding.

5. Quality inspection: Check appearance, dimensions, physical properties (stiffness, pressure resistance), and hygiene indicators.

6. Packaging & storage: Wrap cups in film or boxes and store them for delivery.

Eco - friendliness. PLA, a biodegradable material, significantly reduces environmental impact by decomposing naturally, unlike non - biodegradable PE.
