A coating composition comprising an acid functional acrylic resin and a silane modified compound is disclosed. Substrates coated at least in part with such coatings are also disclosed.

A coinjection molded multi-layer container includes an inner layer, an outer layer, and a barrier layer. The inner layer includes a first polymeric material and forms an inside surface of the container. The outer layer includes the first polymeric material and forms an outside surface of the container. The barrier layer is located between the inner layer and the outer layer and includes a second polymeric material less permeable to gas than the first polymeric material. The barrier layer is biased toward the inside surface or the outside surface such that the inner layer and the outer layer have different thicknesses.

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.

Provided is a fuel container composed of a multilayer structure containing: an ethylene-vinyl alcohol copolymer (A) layer; an adhesive resin (B) layer; a high-density polyethylene (C) layer; and a resin composition (D) layer, wherein the ethylene-vinyl alcohol copolymer (A) contains 15 to 44 mol % of ethylene, the adhesive resin (B) is a maleic anhydride-modified polyolefin having an acid value of 0.1 to 10 mgKOH/g and containing 1 to 8.5 μmol/g of magnesium element, calcium element, zinc element, or a combination thereof, the resin composition (D) contains the ethylene-vinyl alcohol copolymer (A), the adhesive resin (B), and the high-density polyethylene (C), the thickness of the (A) layer, the (B) layer, and the (C) layer satisfies specific conditions, and the ethylene-vinyl alcohol copolymer (A), the adhesive resin (B), and the high-density polyethylene (C) satisfies specific conditions. The fuel container is excellent in fuel barrier properties and impact resistance and enables stable production.

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 0.05≤V/S≤0.25 (formula (I)).

Sterile container (1) comprising a container body (40) having inner surfaces (2, 4) delimiting a containment compartment (6), wherein at least part of said surfaces (2, 4) is made of a compound material comprising a thermoplastic polymer, a first zeolite and a second zeolite homogeneously dispersed in the thermoplastic polymer, each of said zeolites having a micrometric particle size distribution and delimiting reticular voids in which bactericidal and/or bacteriostatic metal ions releasable from said zeolite are housed. The first zeolite comprises silver and copper metal ions, the second zeolite comprises silver and zinc metal ions. The present invention further relates to a sterile product and a compound material.

A recyclable article includes 50-90 wt % of at least one polyethylene having a density in the range 0.94 to 0.97 g/cm.sup.3. The article exhibits Young's modulus less than 700 MPa; and a haze value less than or equal to 50%. The recyclable article can be included in a film or a laminate. The article can be prepared using a blown film extrusion process.

[Problem] 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. [Solution] 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.

Preforms and methods of processing 2,5-furandicarboxylic acid (FDCA) polymers, such as poly(ethylene-2,5-furandicaboxylate (PEF), to produce preforms and articles, such as containers. The present invention also includes preforms with superior processing characteristics and containers, such as PEF beverage bottles, with superior performance properties.
