L-Bar Shrink Wrap System

L-Bar Shrink Wrap System

Understanding L-Bar Shrink Wrap Sealer

The L-Bar Shrink wrap system is designed with two sealing sides that enclose the packaging film around a product as it passes. The system cuts and seals shrink packaging film with a single action. 

Once sealed, the package continues down the conveyor into the shrink tunnel, where heat is used to create an extremely tight enclosure around the product for uniform protection. The shrink-wrap sealer features a perforator roller that leaves small holes in the film and allows trapped air to vent out as the sealed package passes through the tunnel, preventing air bubbles from forming. 

Understanding L-Bar Shrink Wrap Sealer

Types of L-Bar Shrink Wrap Sealers

Industrial shrink-wrap machinery is available in three types, each of which has distinct operations that influence the overall wrapping process. When it comes to choosing the right type of L-Bar sealer, you must consider the production rate, operation and cost of each model, among other factors. 

Manual L-Bar Sealers

Manual L-Bar sealers involve human labor and are easy to operate. For this machinery, an operator is required to grab and push down the handle to cut and seal the packaging film.

Semi-Automatic L-Bar Sealers

Semi-automatic shrink-wrapping machines require less human operation compared to manual sealers. The machine automatically seals the product after the operator places it in the shrink film. The operator uses a control panel to make adjustments to conveyor speed or temperature as needed.

Semi-Automatic L-Bar Advantage

Semi-automatic L-Bar sealers have higher packaging rates and increased output compared to manual alternatives.

Applications of L-Bar Shrink Wrap Sealers

L-Bar sealers are versatile pieces of machinery that serve various shrink-wrapping packaging applications. These machines create secure, professional-looking packaging for products of different shapes and sizes, making them valuable across many industries. Some industries that utilize the L-Bar shrink-wrap system for packaging include: 

  • Food and beverage
  • Printing
  • Construction
  • Electronics
  • Hardware
  • E-commerce
