L Sealers and Shrink Tunnels

Here at Sontex we aim to offer the most impressive and high-quality l sealers & shrink tunnels at all times. L sealer shrink wrapper machines are used to create poly bags of heat sensitive shrink film around products. Attached Shrink Tunnels then apply heat to the bags, shrinking and tightening the film to provide packaging and protection. L-Sealers are a perfect low volume shrink packaging solution and are able to wrap several products per minute.
