Rulyda Gamma Seal Lids turn standard plastic buckets into airtight, leak-proof storage containers with a simple twist. Made from food-grade HDPE with a signature cross-rib reinforced top, each lid delivers a reusable, tamper-evident seal that keeps contents fresh and protected. Ideal for long-term food storage, pet food, emergency supplies, chemicals, powders, and industrial bulk packaging. Available in multiple stock colors with full OEM customization — custom colors, private labeling, and tailored packaging upon request.
Rulyda Gamma Seal Lids are precision-molded screw-on bucket lids designed to convert standard plastic pails into fully sealed, moisture-proof storage systems. Unlike snap-on lids that loosen with repeated use, our Gamma Seal Lids feature a threaded outer ring that locks securely onto the bucket rim, paired with a twist-in center lid that can be opened and resealed effortlessly — no tools, no rubber mallets, no frustration.
The lid surface is engineered with Rulyda’s signature embossed cross-rib pattern, providing structural rigidity that resists warping, stacking pressure, and impact during transport. Manufactured from 100% virgin food-grade high-density polyethylene (HDPE), the lids are BPA-free, odor-resistant, and UV-stabilized for long-term indoor and outdoor use. They meet international food-contact safety standards, making them suitable for direct-contact storage of dry foods, grains, powders, and liquids.
