  • Patent number: 11761845
    Abstract: A process, product, and system for detecting a defective vacuum in a packaged product. The process may include providing a packaged product including a product enclosed within a packaging article. The packaging article may include a film having at least one layer containing a fluorescence-based indicator. The process may further include exposing the packaged product to incident electromagnetic energy to produce an excited fluorescence-based indicator, such that the excited fluorescence-based indicator emits fluorescent electromagnetic energy; and determining, based on the fluorescent electromagnetic energy emitted by the excited fluorescence-based indicator, that gas is present within the packaging article.

  • Patent number: 11628610
    Abstract: The continuity of a functional layer of a web (32, 60, 78) is assessed by forwarding the web, detecting (42, 63) the presence of the functional layer and a discontinuity and/or a thin region in the functional layer, and generating a signal in response to the discontinuity and/or thin region. The functional layer comprises a detectable component (360) in a thermoplastic composition. The detecting is carried out by a machine vision system capable of detecting the detectable component (360) in the functional layer. The detectable component (360) can be active or passive. Also included are systems for carrying out the process.

  • Publication number: 20220214243
    Abstract: A process for monitoring seal quality of a packaging article. In one embodiment, the process for monitoring the seal quality includes sealing a film to form packaging article and forming a seal area. The seal area is analyzed by a vision system to acquire image data of the seal area. A vision inspection engine analyzes the image date to determine the continuity of the seal, the strength of the seal, or both.

  • Patent number: 11168185
    Abstract: Provided is a process for preparing a PVDC additive blend in which an additive is blended with PVDC under high shear blending to produce a highly uniform blend in which the additive is homogeneously distributed throughout the PVDC. It has been found that performing high shear blending in multiple successive stages in which the concentration of the additive in the blend is reduced in each successive stage helps in prove the uniformity of the PVDC additive blend. For example, the high shear blending may be carried out in 2 to 6 stages, and in particular, from 2 to 4 stages. Also provided is a PVDC additive blend having a uniform blend of PVDC and an additive, such as a blend of a PVDC copolymer of vinylidene chloride and methyl acrylate and a fluorescing agent, such as 2,2?(2,5-thiophenylendiyl)bis(5-tert-butylbenzoxazole).

  • Publication number: 20210138771
    Abstract: An autoclavable film has a seal layer, a first tie layer, a barrier layer, a second tie layer, and a skin layer. The seal layer, skin layer, first tie layer, and second tie layer each comprise a polymer having a melt point <121° C. The seal and skin layers comprise the polymer at 5-80 wt %; the tie layers comprise the polymer at 50-100 wt %. The barrier layer comprises PVDC and/or amorphous polyamide. A packaging article is made from the autoclavable film. A retort process comprises placing a product in the packaging article, sealing the article closed, and heating the packaged product to a temperature of at least about 121° C. for ?30 minutes.
