Shrink wrapping involves a process wherein heat-sensitive films are used to cover products before heat is applied to shrink the film and form an airtight wrapping around products. This is also a process of an automatic shrink wrap machine and heat shrink wrapper.

These machines usually comprise two integrated pieces of equipment, namely a sealer and a shrink tunnel. The most used sealers are L-Bar Sealers, Side Sealers, and Sleeve Sealers that can apply and shrink wrap films such as PE, PVC, BOPP, and POF in a safe and efficient manner. Our industrial shrink wrap machine options are safe and effective for mass production usage for our customers.

Packaging Machines USA is the premier choice for our North American customers interested in purchasing full-service and functional shrink wrap equipment and shrink wrapping machine options for their business. Whatever consumer products you need to pack in scale, we have you covered.

L-Bar sealers are commonly used to secure boxes, unitize canned goods and beverages, provide additional protection, tamperproof sealing, and wrap promotional and sample packaging.

Ideally suited to medium and large scale shrink wrap applications, these sealers can shrink wrap small to medium-sized goods like produce, electronic goods, tea boxes, small consumer goods like aerosol containers, bags and pouches, bottles, cans jars, blister packs, cartridges, cups, trays, tubes and vials, etc.

• Product-sensing horizontal and verticals eyes, and time relay ensures superior packing quality whilst preventing inconsistent film applications, in-transit movement, product tampering and damage
• Optimal control of low voltage impulse sealing system with PLC and micro-processor for ideal graphics preservation and a tight, appealing wrap without creases or tears
• Flexible collating and metering technology with built-in photocell product sensor can handle a wide range of packaging goods
• Optional multi-stream packaging alternative can be utilised with appropriate multi-lane conveyors and infeed rails for increased efficiency during packaging runs
• Accelerated packaging speeds can achieve up to 150 cycles per minute
• Unwind systems boast an adjustable, servo motor powered film splitter that can work with all types of shrink films for easy film loading and changeovers, and eliminates too tight or too loose film applications
• Infeed and dispatch conveyor speeds, conveyor run time, dwell time and sealing temperature is adjustable
• Self-centering film drive down systems with automated edge guidance and film tracking
• Automatic collection of excess wrapping material to reduce injury and clogging of waste
• Durable stainless-steel design can fit any medium or large-scale operation

By integrating a Shrink Tunnel into your packaging line, time and labour expenses are severely reduced as production efficiency increases exponentially.

Capable of functioning at high speeds, L-Bar sealers are best suited for heavy-duty, everyday use and are placed in front of a shrink tunnel. They use soft feed conveyors to carry products into the system and guides position them inside the shrink film.

L-Bar sealers use an adjustable sealing arm that comprise two sealing bars in the shape of an inverted L, also known as an impulse sealer, that automatically wrap products inside a bag made of shrink film before a heating element, also called a wire, seals, and cuts the film pouch in one go.

Thereafter products are moved down another conveyor to enter the heat shrink tunnel where the sealed film uniformly shrinks around the products.
