  • Example 1 A packaging film (a multi-layer polyolefin packaging film having a thickness of from about 2.25 mil to about 2.75 mil) was perforated using a laser to form a series of five tear lines. In forming the perforated tear lines, lasers were cycled between ON and OFF positions as the film was passed through the perforation system. Perforated regions formed by turning the laser ON for 1 .5 mm were separated by unperforated regions obtained by turning the laser OFF for 2.0 mm. A portion of the packaging film was divided into 10 samples (each sample containing a 1 -inch wide strip of material) and the tensile strength at a tear line of each sample was measured by pulling the film at 2 inches per minute in accordance with ASTM D 882. The average tensile strength at the tear line was measured to be between about 3.9 lbs/in 2 and about 4.1 lbs/in 2 .

  • the remainder of the packaging assembly also retained its structure and strength after removal of one or more rows of cans.
  • Example 2 A packaging film (a multi-layer polyolefin packaging film having a thickness of from about 2.25 mil to about 2.75 mil) was perforated using a laser to form a series of five tear lines.
  • lasers were cycled between ON and OFF positions as the film was passed through the perforation system.
  • the perforated regions of the outer tear lines were formed by turning the laser ON for 1 .25 mm followed by turning the laser OFF for 2.0 mm to obtain unperforated regions.
  • the perforated regions of the inner tear lines were formed by turning the laser ON for 1 .50 mm followed by turning the laser OFF for 2.0 mm to obtain unperforated regions.
  • a portion of the packaging film was divided into 10 samples (each sample containing a 1 -inch wide strip of material) and the tensile strength at the outer tear lines was measured by pulling the film at 2 inches per minute in accordance with ASTM D 882. The average tensile strength at the outer tear lines was measured to be about 4.3 lbs/in 2 .

  • the remainder of the packaging assembly also retained its structure and strength after removal of one or more rows of cans. It was also observed that the outer tear lines were a little stronger than the inner tear lines, but each tear line was capable of being torn at the user's discretion.

  • a portion of the packaging film was divided into 5 samples (each sample containing a 1 -inch wide strip of material) and the tensile strength of each sample was measured by pulling the film at 12 inches per minute.

  • a second portion of the packaging film was shrink wrapped around six rows of beverage cans (two cans in each row) to form packaging assembly having tear lines centered between each row of cans.
  • the narrow regions of the tear lines (regions 1 , 3, and 5) were centered laterally over the tops and bottoms of the cans, and the wider regions of the tear lines (regions 2 and 4) were centered along the longitudinal sides of the cans.

Rows of cans were capable of being torn from the packaging assembly through the application of force at any of the tear lines.

  • top regions regions 1 , 3, and 5 were easier to break and tear (e.g., for the insertion of one or more fingers to initiate a tear in the film) as compared to the side regions, but both regions were capable of being torn at the user's discretion.
  • Example 4 A packaging film (a multi-layer polyolefin packaging film having a thickness of from about 2.25 mil to about 2.75 mil) was perforated using a laser to form a series of six tear lines.

Abstract

La présente invention concerne un ensemble de conditionnement pouvant comprendre une pluralité de contenants et un film. L'ensemble de conditionnement peut en outre comprendre une ou plusieurs lignes de séparation disposées entre des contenants adjacents, ou entre des rangées adjacentes de contenants. Les lignes de séparation peuvent être constituées de lignes de séparation en pointillés ou de lignes de séparation perforées. Les entailles ou perforations peuvent être formées par un laser, une lame ou par tout autre moyen. Un ou plusieurs contenants peuvent être retirés de l'ensemble de conditionnement par déchirement du film le long de la ligne de séparation.
