Kind code of ref document : A1. Effective date : A wall material for a construction of a flexible container that is designed to be openable by tearing is formed by providing a flexible film for forming a wall of the container, providing a tear barrier element having greater tear resistance than the wall film, locating the element on or within the film to define a tear path thereon, and fixing the element to the film.
The invention provides a method of constructing a flexible packaging unit to facilitate controllable opening thereof by tearing. Further, the invention provides a flexible packaging unit incorporating tear control mews for facilitating its controllable opeung. Means for controlling the direction of tearing of a tearable packaging unit have been previously proposed.
The present application is a Divisional application of U. The claimed invention relates generally to equipment for applying tear tape to a packaging substrate, such as ream wrap, paper or film products, or any packaging materials. The claimed invention generally relates to equipment that interfaces and cooperates with rewinding, wrapping, or packaging equipment.
This is a continuation of U. Teartapes are known to provide a means of facilitating the opening of packages such as packs of cigarettes, confectionery and the like including overwrapping formed from filmic packaging materials. They are adhered to the surface of the packaging material in a manner such that, in use, an end of the teartape can be pulled so as to tear the packaging material underlying the teartape to allow access to the contents.
This invention relates to flexible packaging units intended, to be opened by tearing and to means for controlling the opening by tearing. The invention provides a method of constructing a flexible packaging unit to facilitate controllable opening thereof by tearing. Further, the invention provides a flexible packaging unit incorporating tear control means for facilitating its controllable opening. Means for controlling the direction of tearing of a tearable packaging unit have been previously proposed.
Sculpted perforated header for reclosable packages. Patent number: Abstract: A machine direction method of manufacture of reclosable packages is disclosed wherein a semi-circular or similarly shaped perforated pattern is punched in the web in registration with the package side seals.
