SHM automatic tableware laminating equipment has become essential for producing high edge dinner plates, disposable tableware. This advanced laminating machinery efficiently applies a protective coating to biodegradable plates, bowls, and trays, enhancing durability and heat resistance. It caters specifically to the rising global demand for sustainable food packaging solutions.

One notable example is the disposable plate coating machine, designed to laminate paper and pulp-based tableware with environmentally friendly films such as PLA (Polylactic Acid). This disposable coating machine ensures that the end products are water-resistant, oil-proof, and microwave-safe, making them suitable for various food service applications.

The PLA film laminating machine for tableware offers exceptional precision and consistency. PLA film, derived from renewable resources, is not only biodegradable but also provides excellent sealing performance. The PLA laminating machine is equipped with automatic feeding, heating, and cutting systems, ensuring high production efficiency while maintaining the eco-friendly integrity of the products.

Requirements for Automatic Film Lamination and Edge Trimming of pulp molded Tableware Trays

To ensure high efficiency and excellent results in automatic film lamination and edge trimming, pulp molded tableware trays should meet the following key conditions:

1. Good Surface Flatness

Smooth and even surface with no significant bumps or irregularities to ensure tight film adhesion and avoid bubbles or wrinkles.

Moderate surface roughness; surfaces that are too smooth may reduce film adhesion.

2. Neat and Uniform Edges

Consistent edge thickness with no burrs or significant defects to ensure precise positioning during edge trimming.

Clear cutting lines to help machines identify and follow the trimming path accurately.

3. Stable Dimensions and Shape

Minimal dimensional tolerance with stable shapes to ensure accurate positioning on conveyors or in clamps, preventing alignment errors.

For irregular-shaped trays, clamping points or positioning holes should be considered during mold design to aid precise handling by automation equipment.

4. Adequate Hardness and Toughness

Moderate hardness and good toughness to prevent cracking or breaking during the trimming process, ensuring a high product yield.

Use of high-quality pulp materials ensure the structural stability of the product after molding.

5. Suitable film adhesion

Choose a film that is highly compatible with the pulp material, such as PLA, EVOH or PE film, to ensure that it is not easy to fall off or wrinkle after high-temperature lamination.

The product itself must have a certain temperature resistance and adsorption so that the film and the product can fit firmly under hot pressing conditions.

6. Reserve trimming margin

5-7mm trimming margin should be reserved on the edge to adapt to the blade position of the automatic trimming machine to ensure that the edge of the product is neat after cutting.

7. Waterproof and oil-proof performance design

Adding waterproof and oil-proof agents (such as plant wax and PLA coating) can improve the protective performance of the product after lamination and meet food grade requirements.

If a certain link is found to be ineffective during production, it is necessary to optimize it one by one from aspects such as product design, material selection, and mold accuracy.
