Thermoplastic films and bags with complex stretch patterns and methods of making the same

A thermoplastic film which exhibits elastic-like behavior along at least one axis when stretched or elongated and then released. The thermoplastic film comprises a plurality of raised rib-like elements extending in a direction perpendicular to a main surface of the thermoplastic film. The thermoplastic film further includes a plurality of web areas positioned about the plurality of raised rib-like elements. The plurality of raised rib-like elements and plurality of web areas are arranged in a complex pattern. The complex pattern provides visual and tactile cues as the films are stretched or elongated. The complex pattern can cause the thermoplastic film to have a complex stretch profile.

20170361587 · 2017-12-21 ·

The present paper cup comprises a cup body, and the cup body comprises inner paper and outer paper. There are hollow bulges on the outer paper, and the outer paper forms a connecting part. The inner side of the connecting part bonds to the outer side of the inner paper, and the cup rim of the outer paper extends to the cup rim of the inner paper. In addition, the outer side of the cup rim of the inner paper bonds to the inner side of the outer paper, and both cup rims of the outer paper and the inner paper bend outward to form a double layered crimping. The manufacturing process for the present paper cup includes: paper preparation, rolling, composition, sheet cutting, forming, molding and etc.

Sheet processing apparatus, image forming system, and pair of rotating members
09802354 · 2017-10-31 · ·

A sheet processing apparatus includes a rotating member, a switching unit, and a pressing unit. The rotating member is rotatable and has a facing portion that faces a fold section of a sheet. The rotating member rotates so as to switch the facing portion to another facing portion. Each facing portion is provided with a protrusion. A set position of the protrusion in an axial direction varies from facing portion to facing portion. The switching unit rotates the rotating member so as to switch the facing portion that faces the fold section. The pressing unit presses the protrusion of the facing portion against the fold section.

Thermoplastic bags with complex stretch patterns

A thermoplastic film which exhibits elastic-like behavior along at least one axis when stretched or elongated and then released. The thermoplastic film comprises a plurality of raised rib-like elements extending in a direction perpendicular to a main surface of the thermoplastic film. The thermoplastic film further includes a plurality of web areas positioned about the plurality of raised rib-like elements. The plurality of raised rib-like elements and plurality of web areas are arranged in a complex pattern. The complex pattern provides visual and tactile cues as the films are stretched or elongated. The complex pattern can cause the thermoplastic film to have a complex stretch profile.

THERMOPLASTIC BAGS WITH PHASED DEFORMATION PATTERNS

Thermoplastic bags with phased deformation patterns are described. In particular, one or more implementations comprise thermoplastic bags with ring rolling, SELFing, or other deformation patterns phased or aligned relative to the sides of the bags. The phased deformation patterns can allow for reducing or eliminating deformation patterns in areas of the thermoplastic bag in which side seals or other seals are formed. Additionally or alternatively, the phased deformation patterns can provide for zones that provide differing properties (e.g., functional or aesthetic). Such zones can vary aligned along a width of the thermoplastic bag and optionally also vary along a height of the thermoplastic bag. The differing zones can provide the thermoplastic bags with phased deformations that provide leak prevention, liquid containment, and other benefits.

Films and bags with billow pockets for capturing liquids

A multiple-ply thermoplastic film which exhibits elastic-like behavior along at least one axis when stretched or elongated and then released. The thermoplastic film comprises a plurality of raised rib-like elements extending in a direction perpendicular to a main surface of the thermoplastic film. The thermoplastic film further includes a plurality of web areas positioned about the plurality of raised rib-like elements. The plurality of raised rib-like elements and plurality of web areas are arranged in a complex pattern. The complex pattern, when stretched or elongated and then released, can cause areas of billowing and delamination between plies of the multiple-ply thermoplastic film. The resulting billowed and delaminated areas form billow pockets for capturing liquids that can capture liquids when one of the plies is punctured.
