Square Plastic Containers: Benefits, Uses and Selection Guide

Square containers are plastic packs with a square cross-section and four flat sides; their flat surfaces make them attractive for labelling, printing and orderly stacking. At Jetpak Plastik, square containers are made of PP (polypropylene) by injection moulding, and locking lid and IML options can be planned together.

Advantages of Square Containers

• Flat surfaces: Four flat sides offer a wide, regular area for labels and IML decoration.
• Space use: Straight edges have the potential to use shelf, carton and pallet space efficiently. Actual efficiency depends on size and packing plan.
• Modern look: The square shape can give a brand a distinctive, contemporary appearance.
• Lid options: On locking-lid models, the lid is designed to close firmly on the container.
• Portioning and display: A regular shape can make it easier to place containers side by side and to portion products.

What Are Square Containers Used For?

Square plastic containers are commonly used for dairy products, cheese, salads and deli, ready meals, desserts, dry foods and some non-food products. Suitability depends on filling temperature, product consistency, shelf life and storage conditions.

6 Criteria for Choosing Square Containers

1. Volume and inner dimensions: Should suit how the product is filled, portioned and used.
2. Corner and edge design: Affects ease of filling, emptying and cleaning.
3. Lid type: Locking or plain lid, depending on use frequency and security needs.
4. Decoration: Plain, printed or IML-labelled, depending on shelf impact goals.
5. Filling line and stacking plan: Check compatibility with your line and your carton/pallet layout.
6. Food-contact needs: For food packaging, clarify target-market requirements at the quotation stage.
