Title:
CHEMICAL-RESISTANT BLOW-MOLDED LAMINATE CONTAINER LEACHING FEW IMPURITY PARTICLES
Document Type and Number:
WIPO Patent Application WO/2017/216827
Kind Code:
A1
Abstract:
The present invention is a chemical-resistant blow-molded laminate container that, from the inside to the outside of the container, is laminated from an inner layer one (a fluorine resin that does not have an adhesive functional group, is additive free, and has a heating loss of 0.20 mass% or less), an inner layer two (a fluorine resin that has an adhesive functional group, is additive free, and has a heating loss of 0.40 mass% or less), a barrier/adhesive resin layer (a polyamide that does not contain additives), an adhesive layer (an anhydrous-maleic-acid-modified polyolefin resin), a barrier layer (an ethylene vinyl alcohol copolymer resin), and an outer layer one (an ultra-high-molecular-weight high-density polyethylene resin that includes a light-blocking pigment and an anhydrous-maleic-acid-modified polyolefin resin). The container has a visible light transmittance of 1% or less and an ultraviolet transmittance of 1% or less. The quantity (number/mL) of impurity particles leached by the container after 30 days of storage at 23℃ and 40℃ is 5 or less and 10 or less, respectively. The container has excellent ultraviolet-blocking properties and oxygen-barrier properties and leaches few impurity particles. The contents of the container are not visible.
