Poly Seal Screw Caps for Growler Bottles and Jugs (24 Pieces)

The convex details on the product increase friction and make it easy to twist open the cap. The product is made from low-density polyethylene to provide good torque retention. A raised ridge across the entire circumference makes it easier to hold and airtight. The sturdy plastic material ensures these black plastic lids are reusable and durable, with no risk of rusting over time. Before purchasing, ensure the diameter of the bottle mouth is 38mm, as the cap will not fit otherwise.

The cone-shaped design allows for a tight closure when inserted into the sealing area, preventing liquid leakage, carbonation loss, and gas leakage, providing an effective air-tight seal. The black seal screw cap features a raised ridge across the entire circumference, making it easier to hold and seal.

These 38mm poly screw caps can be used in a wide range of industries, providing a good sealing effect. They can also serve as replacement caps for your 38mm wide glass growler bottles and similar containers.

The package includes 24 pieces of poly seal screw caps, providing multiple quantities to keep an extra on hand just in case. This can meet your daily food sealing and liquid sealing needs.
