How to Seal Drum Liners

Unlike many other styles of Mylarfoil bags, drum liners present some challenges when it comes time to seal them closed. This is in part due to their cylindrical shape and in part because these liners are often placed and filled inside heavy barrels prior to sealing.

How to Seal Drum Liners

Choosing between heat seal, bag clip, or drum lid.

Heat Sealers

The recommended method for sealing Mylar drum liners would be a heat sealer. IMPAK offers a wide range, from handheld units with 6” seal bars to large frame vertical sealers which a 55-gallon drum can be positioned under. [See All Heat Sealers]

Bag Clips

When used properly, bag clips can offer an air-tight seal. They are easy to use and reposition, and they are extremely cost-effective. Size is the biggest challenge with bag clips as they are not as wide as the bag and require corner-cutting or bag folding. [See All Bag Clips]

Drum Lids

In the case where drum liners are being used more for protection of the can than the product inside, the bag may be folded over the sides of the can and the lid placed on top. This drastically undermines the full potential of the high-barrier drum liner, but for many processes is satisfactory and convenient.

NOTE: not all drum liners are able to fold over the top. Discuss what drum size and liner size you are interested in purchasing and our team can confirm or start a sample order for you to test.
