This bar expels all surplus air from the package prior to strap tensioning, ensuring a firm result is achieved without damage to the material during the tensioning stage.Ī bench mounted pressure-sensitive tape dispenser specifically designed to seal the necks of filled polythene bags, a typical example being bags containing bread, fruit or vegetables. Arch strappers can also be fitted with a pneumatically powered pre-compression bar, for strapping compressible materials such as corrugated board. These strappers can be used in a semi-automated environment where a packer manually places the carton onto the sealer, or in a fully automated packing line. For heavier packages the belt driven table can be replaced with a roller driven table. Multiple sensors enable two or more straps to be applied to a package at given spacing. The powered table then continues to feed the package onto a conveyor system. More advanced models feature belt driven tables which automatically feed the package through the arch until a sensor detects it is in the correct position to be strapped and the strapping cycle occurs automatically. Following the strapping cycle, the package may be lifted off the table or pushed through the arch onto a receiving conveyor. In their most basic configuration, arch strappers have a static table onto which the operator manually loads the package. ![]() Strap tension can be adjusted but no further adjustment is required between varying package sizes. On activation, the strapping is tensioned, sealed and cut, then reloaded onto the arch. With an arch strapping machine, the strap is preloaded onto a vertical arch above the table, under which the package is placed. Staple gun featuring a jaw with a raised anvil against which the stapling mechanism crimps the staple, enabling obstructions such as the lipped edges of blister packs to be overcome. Use of a conductive metallised laminated layer or surface coating to direct any electrical energy away from the packaging's sensitive contents also known as the Faraday Cage Principle. Having a very high electrical resistance and by slow dissipation of any electrical charge, preventing the rapid discharge of electrical energy that can damage sensitive components.Ĭontaining or coated with a substance that reduces the risk of tribocharge - generation of a static charge by surfaces being rubbed together or parted. Having properties that prevent, dissipate or shield from a static electrical charge that may cause damage to sensitive electronics or create a hazard in highly flammable or explosive environments. ![]() The coating's water-repellent properties also reduce the risk of water damage due to capillary action through the load. ![]() Heavy imitation kraft paper, coated on both sides with a non-slip, non-adhesive coating that maintains load stability up to a tilt angle of 45 degrees. Film puncture after use reduces recycling volumes.Īdhesive-backed solid aluminium foil tape is a technical pressure-sensitive tape used extensively in the construction and installation sectors, offering excellent water and heat resistance. The pillows feature high puncture-resistance, low compression rate and high recovery rate. Water-based, pressure-sensitive self-adhesive substance resistant to discoloration caused by age and sunlight.Ī high-bulk void fill alternative to bubble film, an air pillow system converts a perforated roll of specialist film into fully inflated, sealed air pillows, rapidly and on demand. Although not as white as bleached tissue paper, acid-free tissue has a pH value of 6-7 (neutral) and is therefore more suited to archival work and packaging of sensitive surfaces such as precious metals and plated articles.
