L BAR SHRINK WRAP L BAR SHRINK TUNNEL
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.
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.
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.

- 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.

By integrating a Shrink Tunnel into your packaging line, time and labour expenses are severely reduced as production efficiency increases exponentially.
Side sealers usually come in two automatic operational designs, namely intermittent motion and continuous motion shrink wrappers.
Depending on production needs, either a two-belt sealer or three-belt sealer can be utilised to eliminate one infeed conveyor for a more efficient wrapping line.
Although a two-belt sealer is more compact than a three-belt sealer, a three-belt sealer is slightly larger and has the added capability of spacing products accurately before they enter the wrapping station.
Since most Side Sealers are sensor-controlled to accommodate both manual or automatic loading, they receive products from an infeed conveyor according to collation specifications. Â
Using a set of horizontal and vertical product-sensing photo-electric eyes, and a time relay, Side Sealers use up to a 1100 mm wide horizontal sealing bar to apply continuous tubes of heat-sensitive wrapping films like PE, PVC, BOPP, and POF to products.
Virtually any product size and length can be wrapped according to a controlled film feeding speed that provides a more cost-effective film application.
Next, the end seal, and side seal is applied with a vertical state-of-the-art thermostatic side cutter. Packages are then separated into individual units with a cross-seal further down the line before products are moved through to the shrink tunnel.
SLEEVE SEALER SHRINK TUNNEL
Sleeve Sealer and Shrink Tunnel is a common way of packaging large products with many benefits. The machine can automatically feed, transport, seal and shrink efficiently. Shrinkable materials such as PE, PVC, BOPP, POF film are optional to choose depending on the standard and purpose of packaging. As a packing machine, the heat shrink wrapping machine can make a high standard package with great capacity. The wrapped products are waterproof and dustproof, clear or designed, and neat packaging material.

By integrating a Shrink Tunnel into your packaging line, time and labour expenses are severely reduced as production efficiency increases exponentially.
Automatic in-line Sleeve Sealers are the ideal shrink wrapping solution for high production volumes of a wide variety of goods, mainly for display, transportation, and distribution purposes.
Products are fed from an inverter-driven, heat-resistant mesh belt conveyor. Smart photo-electric sensors relay product instabilities to the onboard micro-controller that automatically maintains product alignment as goods move along the line to the sealing chamber.
The sealing station is fitted with top and bottom film roll holders that are designed to create a curtain of PE, PVC, BOPP, or POF shrink film at the mouth of the sealing chamber. Products pass through this curtain where a two-way vertical drive system enables the sealer to create a sleeve around them.
With the help of product pack clamps, sleeves can be formed in either long, single or multi-row, or collated tray formats, in effect leaving two small openings on opposing sides of the wrapped products.
Sleeve Sealers use product-sensing horizontal and verticals eyes, coupled with a time relay and a specialised, adjustable sealing blade that can be adjusted according to product size. This helps to ensure consistent, neat, and durable wrapping applications that will prevent in-transit movement, product tampering and damage for when goods are dispatched.
Additional guides, pad-feeding magazines, dye cut cardboard sheets, and stacking mechanisms can form part of the packaging process before the packaging enters a shrink tunnel for final shrink wrapping.

All individual modules that comprise our Shrink Wrap range like infeed and discharge conveyors, multi-lane conveyors, dual infeed rails, and pack cooling racks are available in different versions according to your production requirements.
For large scale operations, automated shrink wrap machines are required to shrink wrap products in a quick, efficient matter.
Loose products start off by being collated before tray packing and shrink wrapping takes place. Shrink wrap materials are usually supplied in flat roll stock, center-folded film, and pre-formed shrink bags.
Unlike flat roll stock shrink wrap that is wrapped around a product, center-folded machines are supplied with a roll of shrink wrap plastic that is folded in half and placed in the center of the machine. All open edges of the shrink wrap are sealed to form a bag before the packaging is heated to shrink the bag around the product.
An alternative is pre-formed bags that feature one open end where the product can be inserted before heat sealing and shrink wrapping takes place. Depending on the size and shape of goods, industries can make use of a L-Bar Sealer,  Side Sealer, or  Shrink Tunnel, coupled with a to deliver effective shrink wrapping processes.
SHRINK TUNNEL SHRINK WRAP SHRINK TUNNEL
Shrink tunnels are auxiliary equipment that can be integrated into the shrink wrapping processes of large-scale, industrial operations, and they are easily paired with either our L-Bar Sealer, Side Sealer, or Sleeve Sealer line to boost efficiency.
A variable-speed roller conveyor with heavy duty 1-inch silicone-coated steel rollers move shrink-wrapped packages into the temperature-controlled shrink tunnel. Inverter-driven heating fans then circulate an even distribution of low-turbulence hot air around the film-wrapped products in order to create a compact shrink-fit.
Once complete, an airflow recovery system helps to save energy by recovering the circulated hot air. A twin-fan cooling system then blows cooler air around the shrink-wrapped products to ensure that the packaging remains stable after shrinking. This is also done to avoid inconsistent shrinkage and burns before products are transported out onto an aluminium pack cooling rack or receiving table.
