摘要： A packaging article has tear initiators for initiating a manual tear that can be propagated to open a package and allow a product to be readily removed therefrom, without the use of a knife or scissors or any other implement. The packaging article is made from a heat-shrinkable multilayer film having at least one layer containing an incompatible polymer blend, and/or a layer containing an inorganic filler, and/or a layer having a high Young's modulus. The film also has a Peak Load Impact Strength of at least 50 Newtons per mil, The tear initiators can be used to generate a manual machine direction tears to open the package, with the manual machine direction tear being capable of propagating in the machine direction to the opposite edge of the packaging article. A process for making a package and manually opening the package is also disclosed.

摘要： A heat-shrinkable bag has a means for initiating a manual tear that can be propagated to open the bag and allow a product to be readily removed therefrom, without the use of a knife or scissors or any other implement. The bag is made from a heat-shrinkable multilayer film having a Peak Load Impact Strength of at least 50 Newtons per mil. The means for initiating tearing results in a first tear in the first side of the bag, and a second tear in the second side of the bag. The first tear and the second tear are each capable of being manually propagated through a heat seal and across the bag, or down the length of the bag, with the tear being capable of being manually propagated through and to an opposite bag edge, so that the product inside a package can be readily removed from the bag. A process for making a package and manually opening the package, comprises placing a product inside the bag, sealing the bag closed, shrinking the film around the product, manually initiating and manually propagating the first and second tears, and readily removing the product from the bag.

摘要： A heat-shrinkable packaging article has one or more tear initiators for initiating a manual tear that can be propagated to open a package and allow a product to be readily removed therefrom, without the use of a knife or scissors or any other implement. The tear initiators are present in a skirt and/or header of the article. The skirt and/or header has a first side and a second side. In one embodiment, some or all of the first side of the skirt and/or header can be heatset in order to reduce the shrink and curling of the skirt and/or header. This improves identification and utilization of the tear initiators by a consumer upon shrinking the packaging article around the product. In another embodiment, the skirt and/or header has a plurality of pairs of tear initiators to allow portions of the package to be torn off to expose a portion of the product that can then be sliced off while the remainder of the packaged product remains covered by a remainder of the film.

摘要： Various embodiments of the present invention are generally directed to an easy opening packaging article, such as an end-seal bag or the like, having a tear initiator and one or more grip assisters. According to various embodiments, the tear initiator and grip assisters are configured to assist a user in opening the packaging article. In particular, the grip assisters are configured to reduce the likelihood that a loose piece of plastic is generated during the opening process, and to reduce the likelihood that undesired tears in the packaging article are generated during the opening process.

摘要： An easy open, hermetically sealed, display package made from a single sheet of thermoplastic, gas barrier, heat shrinkable film is provided. The sheet is folded to form one end of the package, the fold being spaced apart from a seal parallel to the fold line with the material between the seal and the fold line being unshrunken and the remainder of the material being shrunk around the product and sealed on all sides. A unshrunken strip of plastic material having a line of weakness is adhered to the unshrunken portion which is also provided with a line of weakness which also corresponds to the line of weakness in the unshrunken strip. The material on both sides of the line of weakness serves as tear tabs.

摘要： A process for removing creases from a film eliminates a problem in the quality of the heat seal for a patch bag having at least a segment of one or more bag side edges (or the bag bottom edge) covered by one or more patches. The film creases are removed by inflating the film tubing which is later converted to a bag, heating regions containing the creases with a heating means to a temperature which, in combination with the pressure within the inflated tubing, causes the creases to relax. The heated crease-containing regions are then cooled and the inflated tubing is deflated and wound up in a new configuration in which at least one patch covers at least one side edge or the bottom edge.
