Automatic Side Sealer Shrink Wrapping Systems
Continuous, Fully Automatic Wrapping for High-Output Production Lines
Automatic side sealers form a continuous longitudinal seal around products of changing or extended length, then make a cross seal between packs before transfer to a shrink tunnel. The range covers compact integrated seal-and-shrink systems, standard servo side sealers in several conveyor widths and continuous-motion machines for the highest sustained speeds. Each system is specified around product width, height, line speed, film and the required tunnel configuration.
Unlimited Product Length
Continuous side sealing removes the fixed-length limitation of an L-sealer
Widths from 170–950 mm
Machine families for narrow, standard and wide products
Standalone or Integrated
Match with a separate tunnel or choose a compact combined system
Why High-Output Operations Choose Automatic Side Sealers
Keep Products Moving — Automatic product detection, film feeding and sealing reduce operator handling and support sustained inline production. Continuous-motion configurations can reach up to 80 packs per minute where the product, spacing and film allow.
Handle Products of Changing Length — The continuous longitudinal seal means pack length is not fixed by an L-shaped sealing frame. This makes side sealers particularly useful for mixed-length products and long items.
Scale Width and Output Together — Standard servo machines cover product widths from 350 to 950 mm, while continuous-motion models cover narrower high-speed applications from 170 mm and wider products up to 770 mm.
Build the Right Line, Not Just the Sealer — The sealer, film specification, product spacing and heat tunnel are selected as one process. Compact combined systems minimise footprint; standalone sealers provide greater freedom for tunnel sizing and production-line integration.

Key Features of Automatic Side Sealers
Automatic length detection, servo-controlled sealing and machine widths selected around the product range and required line speed.
- Continuous longitudinal side seal accommodates products of unlimited length within the machine’s width and height limits
- Automatic product-length detection synchronised with encoder control
- Servo-driven cross-seal system for accurate, repeatable sealing at production speed
- Adjustable conveyor speed up to 30 metres per minute on the principal machine families
- Recipe storage for repeatable changeovers between established products
- Compact combined system: up to 300 mm product width, 900 mm length and 150 mm height, with an integrated tunnel
- Standard servo range: maximum product widths of 350, 550, 750 or 950 mm; up to 60 cycles per minute
- Continuous-motion range: maximum product widths of 170, 370, 570 or 770 mm; up to 80 packs per minute
- Compatible film includes suitable POF, PP and PE grades; final film and sealing system depend on the application
- Inline integration, installation, operator training and ongoing UK support available
Technical Specifications
Current working specifications. Final requirements will be confirmed against the selected machine configuration.
Ideal for Food, Household Products, Cosmetics, Print, E-Commerce and High-Volume Manufacturing
Side sealers suit regular production where automatic product flow, variable pack length and consistent presentation matter. Product stability, spacing, film and downstream tunnel capacity determine the final line specification.
