Disposable PLA Transparent Dome Lid Half Open Milk Tea Cup Lid

Production Process of PLA Cup Lids

• Raw Material Preparation:

PLA resin, derived from renewable sources like corn starch or sugarcane, is used as the primary raw material.
The PLA resin is processed and compounded to achieve the desired properties such as strength, flexibility, and heat resistance.

• Extrusion:

The compounded PLA resin is fed into an extruder, where it is melted under controlled temperature and pressure.
The molten PLA is forced through a die to form a continuous profile in the shape of the cup lid.

• Thermoforming:

The extruded PLA material is then fed into a thermoforming machine, where it is heated to a specific temperature to become pliable.
A mold, shaped like the cup lid, is used to form the heated PLA material into the desired lid shape through vacuum or pressure forming.

• Trimming and Cutting:

After forming, excess material is trimmed off to achieve the precise dimensions of the cup lid.
Cutting processes may be used to separate individual lids from the formed sheet.

• Printing and Customization:

If required, the PLA cup lids can undergo printing processes for adding designs, logos, or information.
Various printing methods such as flexographic printing or digital printing can be used for customization.

• Quality Control:

Quality control measures are implemented throughout the production process to ensure that the PLA cup lids meet specifications for strength, size, shape, and appearance.
Random sampling, visual inspection, and testing may be conducted to verify quality standards.

• Packaging and Distribution:

Once the PLA cup lids pass quality control checks, they are packed into batches for distribution.
Environmentally friendly packaging materials are often used to maintain the sustainability aspect of the product.

• End Use:

The PLA cup lids are then ready to be distributed to businesses such as cafes, restaurants, and catering services for use with beverage cups.
