Product Description

Stackable injection molding Plastic Storage Container

The underside of the box includes a recessed groove, while the lid includes a complementary lip, allowing you to safely stack boxes, no matter what size. Modular Scaling: Boxes should be made in multiples (such as 1x, 2x, 4x base footprint) in order to fit perfectly into drawers, on shelves or in cabinets.

Suggested Material:

Top Pick: Polypropylene (PP)

Advantages: Very good chemical resistance, highly durable (highly resistant to fatigue on hinges of the lid), high impact strength, and overall lower cost than PET. Also available in transparent/translucent grades.
Disadvantages: Not as easy to make water-clear transparent as PET (has slightly bluish/hazy look).

Luxury Pick: Polyethylene Terephthalate (PET)

Advantages: Superb clarity and gloss, highly rigid and tough, great barrier properties.
Disadvantages: More brittle (impact modification available), higher cost than PP.

Technical Details:

Wall Thickness: Consistent wall thickness (e.g., 1.5mm - 2.0mm) is critical for injection molding to prevent sink marks and warping.
Draft Angles: A minimum of 1-2 degrees of draft on all vertical walls is essential for de-molding without scratches.
Parting Line: Strategically placed to be unobtrusive and not interfere with the stacking function
