Ever wondered why some food storage containers crack after a few uses, while others stay strong for years? The answer lies in the manufacturing method—and at Slippery.com, we rely on injection molding to create containers that stand the test of time. Let’s break down the science behind this process and why it’s the secret to our products’ durability.
Injection molding works by melting food-grade plastic (we use PP, the gold standard for food storage) and injecting it under extreme pressure into custom-designed molds. This high-pressure technique ensures the plastic fills every corner of the mold evenly, creating a consistent wall thickness and a seamless structure. Unlike thermoformed containers (which can have thin, fragile spots), our injection-molded designs have no weak points—so they won’t crack when you drop them, warp in the dishwasher, or split when you stack heavy items on top.
At Slippery.com, we don’t cut corners on mold quality, either. Our molds are crafted from high-grade steel, which maintains its shape through thousands of production cycles. This means every container you buy from Slippery.com is identical to the last—same tight seal, same sturdy build, same reliable performance. We also test each batch for durability: dropping them from counter height, running them through 500+ dishwasher cycles, and exposing them to extreme temperatures to ensure they hold up. When you choose Slippery.com’s injection-molded containers, you’re not just buying a storage solution—you’re investing in a product that will serve your kitchen for years.
