    Abstract: 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.

    Abstract translation: 热收缩袋具有用于启动手动撕裂的装置，其可以传播以打开袋子，并且允许产品容易地从其中移除，而不需要使用刀或剪刀或任何其它工具。 该袋由具有至少50牛顿每密度的峰值负载冲击强度的热收缩多层膜制成。 用于开始撕裂的装置导致袋的第一侧中的第一次撕裂，并且袋的第二侧中的第二次撕裂。 第一撕裂和第二撕裂各自能够通过热密封并穿过袋手动地传播，或者在袋子的长度上手动地传播，其中撕裂能够被手动传播通过并传递到相对的袋边缘，使得 包装内的产品可以容易地从袋中取出。 一种用于制造包装并手动打开包装的方法，包括将产品放置在袋内，将袋密封，将膜收缩在产品周围，手动启动并手动传播第一和第二撕裂，并且容易地将产品从 袋。

    Abstract: A package which allows for butchering and packaging of fresh red meat at a centralized facility is provided which includes a an impermeable tray supporting the product, a first film sealed to the tray for enclosing the product, means defined within the first film for exchanging gases into and out of the package, and a second impermeable film enclosing the first film, such that removal of said impermeable film provides for the exchange of gases into and out of the package. The means for exchanging gases may be perforations defined within the first film, a second highly permeable film sealed to the first film, or an enlarged opening formed within the first film which is enclosed with a patch following adequate gas exchange at retail. Such gas exchange is required to release any low oxygen atmosphere and allow for the introduction of oxygen to the packaged meat product, said means for exchanging gases having a gas transmission rate of at least about 50,000 cc/m2/24 hrs./atm. at 73° F.

    Abstract: A patch bag comprises a lay-flat bag having a patch adhered thereto. The bag has an open top, a closed bottom, and first and second closed sides. The bag is made from a bag film having an inside surface which is sealed to itself. The bag film includes a seal impression on its outside surface. The patch is made from a patch film which is adhered to the outside surface of the bag film. The patch covers at least a portion of the seal impression on the outside surface of the bag film. The patch has a smooth, unimpressed outer surface over the seal impression on the bag film. A process for making the patch bag comprises sealing the bag film to itself and thereafter adhering the patch to the bag, with the patch being adhered over the seal impression on the bag film.

    Abstract: A dual-film package and method for making such package is disclosed which combines the manufacturing simplicity of a package having a single, peelable lid with the consistent peelability of a package having separate permeable and impermeable lids. This is accomplished by providing a support member and a lid having a gas-permeable film and a substantially gas-impermeable film. A first heat-weld bonds the gas-permeable film to the support member and a second heat-weld bonds the gas-impermeable film to the gas-permeable film. The first and second heat-welds each have a bond-strength which is greater than the intra-film cohesive strength of the gas-permeable film so that the lid preferentially delaminates within the gas-permeable film upon peeling, thereby leaving a portion of the gas-permeable film lidded to the support member.
