Automatic L bar sealers are industrial shrink wrapping machines designed for automated product feeding, film sealing, and cutting operations.
They are widely used for medium- to high-volume secondary packaging applications where consistent sealing quality and reliable production efficiency are required.<\/p>

Since 2014, Tengyi has manufactured automatic L bar sealing systems for industries including food, beverage, cosmetics, pharmaceuticals, and consumer goods.
Our machines support different product sizes, packaging requirements, and production speeds with flexible configurations.<\/p>

Common shrink films:<\/strong>
Include POF, PVC depending on product requirements and packaging applications.<\/p>\t\t\t\t\t\t\t\t<\/div>\n\t\t\t\t<\/div>\n\t\t

An automatic L-bar sealer is commonly integrated with a heat shrink tunnel to create a complete shrink wrapping system.
The L-bar sealer completes film feeding, sealing, and cutting, while the shrink tunnel applies controlled heat circulation to achieve a uniform shrink finish.<\/p>

Depending on product size and packaging requirements, We provide different shrink tunnel<\/a> configurations:<\/strong><\/p>\t\t\t\t\t\t\t\t<\/div>\n\t\t\t\t<\/div>\n\t\t
