The first vertical sealed portion forming section is a pair of heat sealing rolls or heat sealing plates, a surface of at least one of which is made from an elastic material softer than a metal.

Polyethylene pouch and the fabrication method thereof

The present disclosure is concerned with a method of forming a seal with a polyethylene based film structure. The polyethylene based film structure has at least one layer formed with an oriented polyethylene having a predetermined melting temperature (T.sub.m). A conductive heat sealing device provides heat to form the seal, where a first sealing bar of the conductive heat sealing device operates at a first operating temperature of at least 10 degrees Celsius (? C.) below the T.sub.m of the oriented polyethylene in the polyethylene based film structure and a second sealing bar of the conductive heat sealing device operates at a second operating temperature of at least 15? C. higher than the operating temperature of the first sealing bar. The seal formed with the polyethylene based film structure retains at least 99 percent of its original surface area prior to forming the seal.

20190255831 · 2019-08-22 ·

A resin film laminated on a support film is attached to the surface of a substrate having a pattern of unevenness. Firstly, the substrate is placed on a stage with the surface side up. Secondly, the resin film is placed so as to face the surface of the substrate and the surface is scanned with a roller while the resin film is pressed against the surface from the side of the support film to bring them into contact with each other. Surface temperatures of the stage and the roller are set to form a temperature gradient such that the temperature of the surface of the resin film to be attached to the surface of the substrate becomes not lower than the softening temperature of the resin film and the temperature of the surface of the support film side becomes lower than the softening temperature of the resin film.

20190241297 · 2019-08-08 ·

An adjustable sealing apparatus and corresponding method of use is disclosed. The sealing apparatus has a variable range of motion programmed to accommodate multiple types of sealing motion, including the reciprocal motion and rotary motion. The proposed design uses two sealing jaw units with each sealing jaw unit located on opposing sides of a continuous layered film. Each sealing jaw unit has a sealing jaw coupled to a distal end of extendable linkages. The sealing jaws are extendable to allow the sealing surfaces to engage one another at a plurality of sealing locations along a plurality of sealing paths. Moreover a control unit is communicatively coupled to each of the sealing jaw units and controls movement of the sealing jaw units to engage one another at one or more of the plurality of sealing locations which enables sealing of the film to produce bags.
