The JX side sealing shrink wrapping machine is a fully automatic, servo-driven packaging line that combines a continuous side sealing machine with a 5030LW heat shrink tunnel. Unlike standard L-bar sealers, the continuous side sealing system allows for unlimited product length — making it the preferred choice for e-commerce cartons, wood flooring, aluminum profiles, rolled textiles, lighting tubes, magazine stacks, and multipack bundles.
Powered by an Inovance (Huichuan) PLC and servo system with German SICK safety sensors and a DuPont Teflon-coated sealing knife, the line delivers precise, high-speed shrink wrapping at conveyor speeds up to 30 meters per minute.

JEWSHIN
Side sealers and L-bar sealers are both shrink wrapping machines, but they serve different production needs. Understanding the difference is the first step in choosing the right equipment.
Side Sealing Machine (This Page) | L-Bar Sealer | |
|---|---|---|
Sealing Method | Continuous longitudinal side seal + cross seal | L-shaped seal frame cuts all four sides simultaneously |
Product Length | Unlimited — sealed continuously as product moves | Limited by sealing frame size (typically ≤500 mm) |
Best For | Long products, variable-length products, high-speed continuous lines | Short to medium products of consistent size |
Speed | Up to 30 m/min conveyor (≈50 packs/min for short products) | 20–40 packs/min (intermittent motion) |
Film Types | POF, PE, PVC | POF, PE, PVC |
Typical Applications | Flooring, profiles, e-commerce boxes, textiles, multipacks | Boxes, trays, books, electronics, cosmetics |
Choose a side sealer when your products are long, variable in length, or you need continuous high-speed output. Choose an L-bar sealer when your products are consistently sized and fit within a standard sealing frame. See also: JEWSHIN L-Bar Sealer Machine (A5645) | Vertical L-Sealer (ZF-A6352)
The longitudinal sealing knife runs continuously along the conveyor. Whether your product is 100 mm long or 2,000 mm long, this machine seals it in one continuous motion without stopping. Product length is limited only by conveyor and tunnel length, not by the sealing mechanism. This is the fundamental advantage of side sealing technology over L-bar sealing, where each product must fit within a fixed frame.
Equipped with an Inovance (Huichuan) PLC and servo system, the sealing motion is precise and fast. The conveyor speed reaches 30 meters per minute — significantly faster than pneumatic machines that rely on air-driven cylinders. Servo control also delivers consistent sealing pressure across the full speed range, which pneumatic systems cannot maintain at higher speeds. For production lines running mixed product sizes, the servo system adjusts sealing parameters automatically via recipe selection on the touch screen.
The sealing knife is protected by German SICK optoelectronic sensors. If the sensor detects an object (or hand) under the blade, it instantly stops the cut — preventing injury and product damage. This is a critical safety feature for production environments where operators interact with the machine during size changeover and maintenance. The SICK sensor is an industrial-grade safety component widely used in European machinery, supporting CE compliance.
The cutter is made of high-temperature resistant alloy steel with a DuPont Teflon coating. This ensures a strong, clean seal without the film sticking to the blade — a common failure point on cheaper machines where adhesive residue builds up on the knife and degrades seal quality over time. The Teflon coating also extends blade life and reduces maintenance frequency.
An automatic film waste winding system, controlled by sensors, collects the trimmed film edge continuously. This keeps the work area clean and prevents film scraps from interfering with the sealing or shrinking process — a practical feature for high-speed continuous production.
Built with a heavy-duty frame and proven drive design, the side sealer is engineered for a normal service life of approximately 10 years under routine production loads — an industrial-grade machine, not a light-duty unit.
The side sealer is paired with the 5030LW heat shrink tunnel, designed to deliver consistent shrinking performance for a wide range of product sizes and film types.
The 5030LW tunnel features a visual inspection window, allowing operators to monitor the shrinking process in real time. This is particularly useful when setting up a new product or film type — operators can see how the film is contracting and adjust temperature or conveyor speed without stopping the line to inspect finished packs.
The tunnel uses double-layer rock wool insulation to retain heat inside the chamber, reducing energy consumption and keeping the workshop environment cooler. For facilities running the shrink tunnel for extended shifts, this directly lowers operating cost and improves operator comfort.
Heating is delivered by stainless steel heating elements for durability and even heat distribution. Temperature is controlled by an Autonics controller with a range of 0–200°C, providing precise temperature management for different film types — POF typically shrinks at 130–160°C, PE at 160–200°C, and PVC at 120–150°C.

What is a side sealing shrink wrapping machine and how is it different from an L-bar sealer?
A side sealing shrink wrapping machine forms a continuous longitudinal seal along one side of the product, then makes a cross seal between packs to separate them. Unlike an L-bar sealer, which uses an L-shaped sealing frame that limits product length to the frame size, a side sealer has no length limit — the sealing knife runs continuously. This makes side sealers the preferred choice for long products (flooring, profiles, rolled textiles), variable-length products, and high-speed continuous production lines.
What does unlimited product length mean?
The longitudinal sealing knife runs continuously along the conveyor. Whether your product is 100 mm or 2,000 mm long, the machine seals it in one continuous motion without stopping. Product length is limited only by the conveyor and tunnel length, not by the sealing mechanism. This is the key advantage over L-bar sealers, which require the product to fit within a fixed sealing frame.
What shrink film types are compatible with this machine?
The machine is compatible with POF (polyolefin), PE (polyethylene), and PVC shrink films. POF is the most common for retail packaging due to its clarity and food-safe properties. PE is used for heavy-duty industrial bundling. The sealing knife features a DuPont Teflon coating that prevents film from sticking during the sealing process, ensuring clean seals across all film types.
What is the conveyor speed and how many packs per minute can it handle?
The conveyor speed reaches 30 meters per minute, driven by an Inovance servo system. Actual packs per minute depends on product length and spacing — shorter products can achieve up to 50 packs/min, while longer products (e.g., 1-meter flooring strips) will naturally run fewer packs per minute but maintain the same conveyor speed. The servo control ensures consistent sealing quality at all speeds.
What safety features does the side sealing machine have?
The machine uses German SICK optoelectronic sensors for knife protection. If the sensor detects an object (or hand) under the sealing blade, it instantly stops the cut, preventing injury and product damage. This is a critical safety feature for production environments where operators interact with the machine during size changeover and maintenance.
Can the machine handle different product sizes without long changeover?
Yes. The side sealing system accommodates products with width plus height under 400 mm and height under 170 mm. Width and height adjustments are tool-free, and the servo-controlled sealing position is set via the touch screen. For production lines running mixed product sizes (common in e-commerce and contract packaging), the side sealer is significantly more flexible than an L-bar sealer, which requires frame changes for different product sizes.
What is the 5030LW shrink tunnel and can I use a different tunnel?
The 5030LW is a heat shrink tunnel with a 1500 × 500 × 300 mm chamber, stainless steel heating elements, and an Autonics temperature controller (0–200°C). It features double-layer rock wool insulation for energy efficiency and a visual window for real-time monitoring. Extended tunnel lengths are available for longer products or higher throughput — JEWSHIN engineers will confirm the right tunnel size based on your product dimensions and line speed.
Can the machine integrate with upstream and downstream equipment?
Yes. The side sealer connects to upstream product feeding conveyors, friction feeders, or manual loading stations. Downstream, it integrates with cooling conveyors, counting systems, inkjet/TIJ/TTO batch coders, carton erectors, and case packers. JEWSHIN can design the complete line layout from product infeed to sealed, shrunk, and cartoned output.
What power supply does the machine require?
The side sealing machine requires 220V, 3 KW. The 5030LW shrink tunnel requires 380V, 3-phase, 16 KW. Voltage can be customized to match your local power grid (110V/415V on request).
Do you provide installation, training, and after-sales service?
Yes — online installation guidance, free engineer training until your team operates confidently, an English user manual, a 1-year warranty, lifetime maintenance, 24/7 English remote support, and overseas engineer service on request.
Does JEWSHIN offer OEM or custom options?
Yes. Conveyor width, tunnel length, film type compatibility, optional coding/labeling integration, voltage, branding, and machine color can all be customized to your specification.
