US Classification:

428 349, 4284744, 4284755, 428 366, 428 367

Abstract:

A multilayer, heat-shrinkable film contains at least one semi-crystalline polyamide selected from the group consisting of polyamide 6, polyamide 66, polyamide 6/66, and polyamide 6/12. The film may have a total semi-crystalline polyamide content of at least 35 volume percent, based on total film volume, and a total free shrink at 185 F. of at least 35 percent. The film may have an FTIR Transmission Absorbance A/Aratio of up to 1. 65. The film may be a retortable film, capable of being used in a process for preparing a retorted packaged product. A process for making a heat-shrinkable annular film containing the semi-crystalline polyamide comprises extruding an annular extrudate downward from an annular die, quenching the annular extrudate by applying a quenching liquid to the annular extrudate, reheating the extrudate to an orientation temperature, and orienting the reheated annular extrudate while the reheated annular extrudate is in the solid state, the orientation being carried out with a total orientation factor of at least 2, to produce a film having a total free shrink at 185 F. of at least 10 percent.

Abstract:

As a first aspect, the present invention is directed to a process for making a heat-shrinkable annular film, comprising: (A) extruding an annular extrudate downward from an annular die; (B) quenching the annular extrudate by applying a quenching liquid to the annular extrudate; (C) reheating the extrudate to an orientation temperature of from 130 F. to 210 F. , resulting in a reheated annular extrudate; and (D) orienting the reheated annular extrudate while the reheated annular extrudate is in the solid state, the orientation being carried out with a total orientation factor of at least 2, so that the resulting oriented, heat-shrinkable film has a total free shrink at 185 F. of at least 10 percent. The extrudate comprises at least one semi-crystalline polyamide selected from the group consisting of: (i) polyamide 6, (ii) polyamide 66, (iii) polyamide 6/66, and (iv) polyamide 6/12. The semi-crystalline polyamide makes up at least 5 volume percent of the annular extrudate.

Abstract:

A multilayer, heat-shrinkable film has a first layer that is an outer film layer and that serves as a heat seal layer, and a second layer comprising at least one semi-crystalline polyamide. The first layer contains at least one member selected from the group consisting of (i) polyolefin having a density of from 0.88 g/cmto 0.917 g/cm, and (ii) ionomer resin. The second layer contains at least one semi-crystalline polyamide selected from the group consisting of polyamide 6, polyamide 66, polyamide 6/66, and polyamide 6/12, with the semi-crystalline polyamide making up at least 50 weight percent of the second layer. The film has a total free shrink at 185 F. of at least 35 percent. The film has a total semi-crystalline polyamide content of at least 35 volume percent. The multilayer, heat-shrinkable film exhibits a percent haze as measured using ASTM D 1003-00, and a percent transparency as measured using ASTM D 1746-97, in accordance with the following equation: % Transparency≧5.33 (% Haze)−31.5 The multilayer, heat-shrinkable film can be used to make a packaging article.

Abstract:

A method for biometric authentication has the steps of sending a confidential communication to an intended recipient through the system, the intended recipient providing one or more biometric identifiers to view the communication, wherein the one or more biometric identifiers are unique to the intended recipient, the system verifying the one or more biometric identifiers against one or more stored biometric identifiers, the system accepting the one or more biometric identifiers further has the steps of the system displaying the confidential communication on the mobile device, and the user continues to provide the one or more biometric identifiers, the system continuously verifying the one or more biometric identifiers while the communication is displayed wherein when the verification is uninterrupted of fails the communication is hidden.
