L-Bar-Sealer (up to 40 cycles/min)

Compact solution for sealing individual products

Clean weld seams, simple operation and high process reliability

The L-Bar sealer is the ideal entry-level solution for a durable, fully automatic packaging process. The sensor-controlled packaging line of the film welding machine can be fed manually or fully automatically. The automatic film welding machine guarantees reliably stable side seams for all films. The film is separated by two permanently heated Teflon knives (L-angle). The half-tube film is sealed by adjustable heat separation. The use of our tube bag machine allows the user to package a wide variety of product formats depending on the respective sealing frame size. The quick changeover to other product formats guarantees efficient and cost-effective operation. With its integrated product centring unit (product weld seam is centred), you get optimum preparation for the shrink process (shrink film packaging).

Frequently asked questions about our L-bar sealer (up to 40 cycles/min)

An L-bar sealer is a packaging machine that seals products in film. The sealing wires are arranged in an L-shape and seal the film on two sides simultaneously. The film is then often shrunk to fit precisely in a shrink tunnel.

Typical uses are:

  • Foodstuffs such as pizza, bread or confectionery
  • Printed products such as books, magazines or advertising materials
  • Cosmetics, DVDs, electronics, household goods

The L-bar sealer is versatile and suitable for many industries.

Depending on product size, film type and degree of automation, the device can shrink-wrap up to 40 packaging units per minute. Ideal for medium to high production volumes in continuous packaging operations.

The following are particularly suitable:

  • Polyolefin fine shrink film (POF)
  • PVC film (optional)
  • Thin PE films (in combination with suitable parameters)

We offer you the right film rolls directly from the manufacturer.

Yes – for perfect packaging results, the L-bar sealer can be combined with a shrink tunnel. This ensures a tight-fitting, visually appealing packaging with a protective function.
