When purchasing or inspecting fan-shaped pieces, the following core indicators will be considered:
The weight and thickness of the base paper directly affect the stiffness and compressive strength of the paper cup.
Coating amount: The weight of plastic coated per unit area (g/m ²). Insufficient film coating can lead to leakage, while excessive coating can increase costs and affect environmental friendliness.
Printing effect: whether the color is accurate, whether the overprinting is precise, and whether there are any dirty spots.
Die cutting accuracy: The size, angle, and arc length of the fan-shaped piece must be highly precise, otherwise it will cause frequent jamming of the cup rolling machine and skewing of the finished cup.
Hygiene and migration: Must comply with national food contact material standards to ensure no harmful substances migrate.
