FAQs – Plastic Square Container Mould Supplier

1. What materials do you recommend for manufacturing square food containers?

We typically recommend Polypropylene (PP) or Polyethylene Terephthalate (PET) as they are food-safe, provide good barriers, and are excellent for thin wall applications using our specialized moulds.

2. Can I get a multi-cavity mould for my square container design?

Yes, we specialize in high-cavitation moulds. We optimize the mould layout and runner system to ensure efficient material distribution and balanced filling across all cavities, maximizing output.

3. How do you ensure the sealing quality of the square container lid?

We incorporate precise features into the mould design, often involving complex shut-off areas and tight tolerances, which guarantee a secure, consistent, and leak-proof seal between the container and its lid.

4. Is thin wall moulding suitable for large square containers?

Thin wall technology is highly effective even for large containers, provided the mould design incorporates efficient injection points and robust cooling systems to ensure structural integrity despite the reduced wall thickness.

5. What information is needed to start a custom mould project?

To begin, we need the 3D container design file (if available), specifications on required volume/output, desired plastic material, and any specific container features like snap-lids or handle placement.
