A bioplastic collapsible dispensing tube may include a collapsible tube having walls that include a bioplastic material; a distal end of the tube that is sealed; a proximal end of the tube, opposite the distal end, that has an opening; a nozzle on the opening; and a closure for the nozzle; wherein, when the closure is opened and the tube is collapsed, flowable material inside the tube is urged out of the nozzle; and the bioplastic material includes a bio resin selected from the group consisting of PEF, PBF, PTF, GPE, GPET, PLA, PDLA, PLLA, PHA, and PHBH. A method may include forming a tube and filling the tube with flowable material from the distal end.
FLUID-CONTAINER AND METHOD FOR CONTROLLING CRYSTALLINITY IN BLOW-MOLDED CONTAINER
A fluid container having a proximal end having an end wall, a distal end having an open-ended neck, and a sidewall extending between the proximal end and the distal end along a longitudinal axis is described. A localized crystallinity of a polymeric material of the fluid container of at least a first region of the fluid container is greater than a crystallinity of a polymeric material of the fluid container of at least a second region. Examples of fluid containers include medical fluid containers, such as medical bottles and syringes, including rolling diaphragm-type syringes, and commercial beverage containers Articles of manufacturer formed form a polymeric material and having regions with increased localized polymeric crystallinity are also described.
CARTRIDGE FOR ELECTROSTATIC SPRAYING DEVICE
A cartridge for an electrostatic spraying device according to the present invention is a cartridge for an electrostatic spraying device, the cartridge comprises a storage bag having a storage section in which a liquid composition is stored, the storage section is surrounded by a joint portion formed by joining a pair of laminates, each of the laminates comprises an innermost layer on the joint portion side, an outermost layer on a side opposite to the innermost layer, and a barrier layer between the innermost layer and the outermost layer, and the liquid composition comprises 50 mass % or more of a volatile liquid agent selected from alcohols and ketones.
Microwaved multi-ply structures, microwaved packages, and methods of sterilization
Multi-ply structures are provided that include a barrier film, which has a first polyester layer and a silicon oxide layer, a first adhesive layer, and a sealant film, where the first adhesive layer is located between the barrier film and the sealant film, and where the multi-ply structure has been microwaved in a pressurized vessel. Packages that are formed from the multi-ply structures are also provided in which these packages are microwaved in a pressurized vessel. Methods for sterilization are also provided.
FILMS FROM RECYCLED POLYETHYLENE
Large volumes of recycled polyethylenes are available for reuse. It would be desirable to prepare films from recycled polyethylene, however, the technical demands for many types of films can make this very difficult. Provided herein are films, for example, stretch films; shrink films; films for vacuum packages and films for dunnage packaging, that may be prepared from a blend of recycled polyethylene with “virgin” polyethylene.
MULTI-LAYER COVERS WITH DETACHABLE SEGMENT AND METHOD OF THEIR PRODUCTION
The invention refers to closures or covers 20 of containers for facial tissues, wipes and in particular wet wipes, diapers and in general items that require to remain within a container 50, with no direct contact with the environment. The cover 20 includes an inner layer 22 and an outer layer 24, both having an inner face and an outer face, whereby the inner faces of the both layers 22, 24 comprise means to adhere to each other. The outer face of the inner layer 22 is at least partially coated with reclosable adhesive to adhere, to a container 50. The inner layer 22 has a detachable segment 35b, which adheres to the outer layer 24 and which has an outer face that is part of the outer face of the inner layer 22 and that it is at least partially covered with reclosable adhesive. The inner layer 22 and/or the outer layer 24 comprises means 34, 36 to allow separation and subsequent withdrawal of the detachable segment 35b from the cover 20. Further, the invention suggests a method for producing a roll with covers 20.
NONWOVEN WATER DISPERSIBLE ARTICLE FOR UNIT DOSE PACKAGING
The disclosure provides a nonwoven web, said nonwoven web including a plurality of fibers including a blend of fiber forming materials, the blend of fiber forming materials including a first polyvinyl alcohol polymer. The blend of fiber forming materials further comprises a second polyvinyl alcohol polymer or does not include carboxymethyl cellulose, hydroxypropyl methylcellulose or starch. The nonwoven web can be water-dispersible, optionally water-soluble, and/or flushable. The disclosure further provides a pouch including a nonwoven web including a plurality of fibers according to the disclosure. In some embodiments, the water dispersible pouch can include a laminate comprising a water-soluble film and a nonwoven web of the disclosure.
RESIN COMPOSITION FOR SEALANT, LAMINATE, PACKAGING MATERIAL, AND PACKAGE
A resin composition for a sealant has excellent heat-sealing strength with respect to a substrate, and a reduced elution amount thereof into normal heptane.
A resin composition for a sealant includes: a resin (A) which is an ethylene-(meth)acrylic acid ester copolymer in which a content of a (meth)acrylic acid ester unit is from 10% by mass to 25% by mass; and a tackifying resin (B), in which a content of the resin (A) is more than 45% by mass with respect to a total amount of resin components in the resin composition for a sealant, and a content of the tackifying resin (B) is from 0.1% by mass to 10% by mass with respect to the total amount of the resin components in the resin composition for a sealant.
METHOD FOR SELECTING POLYESTER FILM, METHOD FOR PRODUCING MULTILAYER BODY, METHOD FOR PRODUCING PACKAGE, AND MULTILAYER BODY
The present disclosure relates to a method for selecting a polyester film in which the polyester film is used as a sealant layer in a multilayer body including a base material layer including a crystalline polyester film, an adhesive layer and a sealant layer in this order, the method including:
a step in which FT-IR analysis is performed on the polyester film by a reflection method, and the crystallinity of the polyester film is measured by the following formula; and
a step in which a first polyester film having a crystallinity of 2 to 15% is selected:
I.sub.1409=p1×I.sub.1340+p2×I.sub.1370 (Formula 1)
Crystallinity[%]=p1×(I.sub.1340/I.sub.1409)×100 (Formula 2)
LAMINATED IRON USED FOR FOOD PACKAGING AND HAVING DURABLE AND HIGH SURFACE TENSION FORCE, AND PREPARATION METHOD
The present invention provides laminated iron having excellent printability and a preparation method therefor. The laminated iron is prepared by using a mode of performing thermal-compounding on a polyester thin film having a durable and high surface tension force and a steel plate, wherein the polyester thin film is prepared by copolymerizing terephthalic acid, isophthalic acid, ethylene glycol and a fourth component and then bidirectionally stretching a co-polymer; a feeding mole ratio is that terephthalic acid:isophthalic acid:ethylene glycol:a fourth component=(135-165):(148-194):(11-15):(0.01-12); the fourth component is selected from one or more of isophthalic-5-sulfonate, 1,4-cyclohexane dimethanol, neo-pentanediol and trimellitic acid; and 800-2000 ppm of SiO.sub.2 in parts by mass is added to a copolymerized polyester by using a mode of in-situ polymerization. The laminated iron has excellent printability and satisfies usage requirements of packaging containers for food, beverage and the like.
