Angel Hair - Thin strands of shrink film on the edges by the seal that can be caused by a variety of issues.
Centerfold Shrink Film - A shrink film folded lengthways and placed on a roll.
Chamber Size - Referring to a shrink tunnel, the chamber is the size of the heated interior area.
Contactor - Electrical relay used to engage heaters, sealers, or blowing fans on a variety of shrink machines.
Control Panel - The main operating panel for a sealer or shrink tunnel often consisting of temperature control, conveyor speed, shrink time, seal time, and more.
Discharge Conveyor - A conveyor belt between an L Bar sealer and shrink tunnel used to transport sealed products.
Entry Conveyor - A mechanically driven product transportation device used to move products into a fully automatic shrink wrap machine.
Exit Conveyor - A mechanically or gravity-driven product transportation device used to move products from a semi-automatic or fully automatic shrink wrap machine.
Film Build Up - The build-up of black film residue on a sealer after multiple seals.
Film Rack - A film holder used to dispense film for shrink wrapping, sealing, and other applications.
Film Separator - A device used to separate centerfold shrink film before sealing and shrinking.
I Bar Sealer - A machine consisting of one heated side used to seal off and enclose products within a flexible plastic film.
Impulse Sealer - A smaller I Bar sealer often used for low production sealing.
Infrared Shrink Tunnel - A form of shrink tunnel often consisting of multiple infrared heating tubes used to heat the inside of the tunnel.
L Bar Sealer - A machine consisting of two heated sides used to seal off and enclose products within a flexible plastic film.
Magnetic Hold - A locking mechanism using magnets to hold down a sealing bar until a seal is completed.
Mesh Belt - A gridded wire belt overlay placed on conveyor roller rods to prevent smaller products from slipping between individual rollers.
Micro Knife/Band Ribbon - A newer form of a sealing element found below sealing bars used to replace sealing wires. Band ribbons are often attached to the mainframe of the machine below the sealing bar. Band ribbons are often thicker and capable of sealing and cutting many more products before replacement is necessary.
Pinwheel Perforator - A wheel-shaped object with sharp points often placed close to the film rack to insert small holes into shrink film. The small holes allow air to escape the sealed package when the heat is applied.
Power Film Unwind - A motorized sealer feature designed to easily unwind film from the carriage for easier use.
Recirculating Shrink Tunnel - A form of shrink tunnel using fans to blow heat within the shrink tunnel continuously.
Roller Rods - Rotating rods often Teflon coated placed on a conveyor chain to transport products through a shrink tunnel.
Seal Time - A specified time set to complete a seal on flexible plastic materials.
Sealing Bar - The top bar on an L Bar sealer or I bar sealer, lowered down to create a seal on flexible plastic film.
Sealing Wire - A heated wire element found on the sealing bar used to apply heat to create a seal on flexible plastic. Sealing wires are available in flat and round wires. The flat wire sealing wires only seal film and are capable of obtaining thicker, stronger seals. Round wire sealers seal and cut the excess film.
Shrink Chamber - A fully enclosed seal and shrink wrapping machine that fills with hot air for a specified time after a completed seal.
Shrink Time - A specified time set to apply heat to a shrink film to obtain the proper shrink rate.
Shrink Tunnel - A heating element commonly used with shrink wrapping, consisting of a conveyor moving products through a heated area to shrink film.
Single Wound Shrink Film - A flat shrink film placed on a roll.
Steam Shrink Tunnel - A form of shrink tunnel using steam to heat the tunnel interior.
Teflon Tape - A PTFE extruded tape with a chemical-resistant surface. Placed over sealing wires and bumpers to reduce film build-up directly on the sealing wire.
Transit Chanel - A ceramic channel used to hold band ribbons in place.
