SEALING FILM SUITABLE FOR FOOD PACKAGING AND PREPARATION METHOD THEREOF
A sealing film suitable for food packaging is disclosed, which adopts the following solution. The sealing film comprises, in sequence, a PET layer, a VMPET layer and a PE layer from outside to inside, wherein the PE layer comprises 100-110 parts of PE, 15-20 parts of EVA, 15-20 parts of EAA, 55-60 parts of HDPE and 10-15 parts of LLDPE in parts by mass. In this manner, the addition of HDPE and LLDPE into the PE layer is intended to enhance the tensile strength of the sealing film.
PACKAGE
A package has a bag body, at least one mouth part member bonded to the bag body, and a contained product being a liquid housed in the bag body. The bag body is formed in a bag shape by using laminates each having a sealant layer and a water vapor barrier layer composed at least of a fluorine-based resin, and by bonding together the sealant layers opposing each other so that the sealant layers are to be located on the inside of the bag body. The mouth part member is sandwiched between the oppositely facing sealant layers and is bonded thereto. The volume V of the contained product housed in the bag body is 0.1-20 cm.sup.3, and the relation between the area S (cm.sup.2) where the bag body is in contact with the contained product housed in the bag body and the aforementioned volume V (cm.sup.3) satisfies 0.05V/S0.25 (formula (I)).
Multi-layer injection molded container
A method for manufacturing an injection molded container includes operating an injection molding apparatus to inject one or more polymeric materials into a mold cavity to form a container. The container includes an energy director ring protruding from an inside surface of the container and extending circumferentially along the inside surface. The method includes welding a filter onto the inside surface by applying a welding force to the inside surface. The energy director ring causes the welding force to be concentrated at a location of the energy director ring, thereby forming a circumferential weld that secures the filter to the inside surface the location of the energy director ring.
Flexible Bags and Products Therein With Extended Shelf Life
This invention relates to extending shelf life of food product such as wine packaged in flexible bags. Oxygen transport into the wine through the flexible-bag walls reduces the shelf life of the product. Similarly, oxygen in air trapped in headspace of a flexible bag packaged with the food product such as wine eventually dissolves into the wine, and consequently diminishing its shelf life. This invention relates flexible bags that provide inert gas cavities around the wine and in the headspace above the wine, and the process of making such flexible bags, such that the total oxygen content inside an unfilled (with product) flexible bag is less than 10%.
Preform extended finish for processing light weight ecologically beneficial bottles
Disclosed are preforms which incorporate improvements in the region of the neck and upper segment of the body to allow the production of lightweight containers, such as bottles suitable for containing water or other beverages. In accordance with certain embodiments, the improvements include a thinner neck finish area than conventional bottles, where the thinner area is extended into the upper segment of the body portion below the support ring. Reducing the thickness in these areas of the bottle allows for less resin to be used in forming the preform and bottle.
Composite preform and method for producing the same, composite container and method for producing the same, and composite container product loaded with beer
To provide a composite preform that can ensure that worsening of the appearance of a surface of a plastic member caused by near-infrared heating prior to blow molding is effectively prevented and that an inner preform is efficiently heated. The composite preform of the present invention includes a preform and a heat-contractive plastic member, the preform including a mouth part; a trunk part linked to the mouth part; and a bottom part linked to the trunk part, and the heat-contractive plastic member being disposed so as to surround the outside of the preform and including at least a colored layer that contains a resin material and a colorant, wherein the heat-contractive plastic member has a near-infrared transmittance of 50% or higher.
MULTILAYER COMBINING BOTH GOOD AGEING PROPERTIES AND RESISTANCE TO BURSTING IN HOT CONDITIONS, THAT CAN BE USED FOR HIGH-TEMPERATURE MOTOR VEHICLE APPLICATIONS
The present invention concerns a multilayer tubular structure (MLT) intended for transporting fluids such as air, oil, water, a urea solution, a cooling liquid made from glycol, a transmission oil cooler (TOC), or an air conditioning liquid, or a fuel such as petrol, in particular bio-petrol, or diesel, in particular bio-diesel, comprising at least one layer (1) and at least one layer (2), said layer (1) comprising a composition comprising: a) at least 50% by weight of at least one semi-aromatic polyamide of formula W/ZT, b) at least 10% by weight, preferably at least 15%, of an impact modifier, c) between 0 and 20% by weight of at least once plasticiser, d) between 0 and 40% by weight of at least one additive, the sum of a) +b) +c) +d) being equal to 100%, said layer (2) comprising a composition comprising a) at least 50% by weight of at least one short-chain semi-crystalline polyamide referred to as (A), said short-chain aliphatic polyamide (A) being of formula X Y/Z, or formula V/Z, b) between 0 and 15% of at least one impact modifier, c) between 0 and 12% by weight of at least once plasticiser, d) between 0 and 40% by weight of at least one additive, the sum a) +b) +c) +d) being equal to 100%.
Powdered Pouch And Method Of Making Same
Disclosed herein are water-soluble films and resulting packets including a water-soluble film coated by a powder, wherein the powder includes a mixture of a powdered lubricant and an active agent. Optionally, the active agent may be encapsulated, e.g. microencapsulated, for release of the active agent through mechanisms including, but not limited to, mechanical rupture, melt, ablation, dissolution, diffusion, biodegradation, or pH-controlled release. Active ingredients described include enzymes, oils, flavors, colorants, odor absorbers, fragrances, pesticides, fertilizers, activators, acid catalysts, metal catalysts, ion scavengers, bleaches, bleach components, fabric softeners and combinations thereof. Examples of packet fills include laundry detergents, bleach and laundry additives, fabric care, dishwashing, hard surface cleaning, beauty care, skin care, other personal care, and foodstuffs.
