What Exactly is an Automatic L-Bar Sealer?

Automatic L-bar sealers are specialized machines that package products in various materials, especially shrink film, via a heated sealing bar. This design allows for swift operation, automatically feeding, sealing, and cutting the film around the product. The term "L-bar" refers to the shape of the heated sealing bar, which facilitates a snug wrap around products' edges.

Types of Seal Bars

Seal bars generally fall into two categories: hot wire seal bars and hot knife seal bars.

Hot Wire Seal Bar

Hot wire seal bars use heated wires to fuse film surfaces together, creating a robust and accurate seal. The melted edges ensure that products remain securely wrapped during transit and storage.

Hot Knife Seal Bar

In contrast, hot knife seal bars melt the film instead of cutting through it, achieving a seamless and airtight seal. This is particularly advantageous for products needing protection from air exposure. They can also be treated with non-stick coatings to prevent adhesion to hot surfaces.

Optional Features for Your L-Bar Sealer

Perforated Roller

This feature allows for the escape of air as products move through the shrink tunnel, helping to prevent air pockets that could harm product integrity. Note that specific films are required for compatibility with perforated rollers, and consulting with a film specialist is advisable.

Selvage Rewinder

The selvage rewinder manages excess film, contributing to a cleaner production area and minimizing waste. This component can be designed for both internal and external installation to the L-bar sealer.

Additional Equipment Requirements

Purchasing an automatic L-bar sealer often necessitates complementary upstream and downstream equipment to ensure seamless production. The listed equipment is just a starting point for considerations.
