[Production Example] Food-Grade Wide Mouth Bottle (PP・EVOH/3 Types 5-Layer Co-Extrusion)

[Plastic Container OEM] Support from prototyping to mass production! Capable of small items, thin materials, and multi-layer molding.

We would like to introduce a case study of the production of food-grade wide-mouth bottles by Daikyo Chemical Co., Ltd. Our customer had requests focusing on deformation prevention during high-temperature filling and heat resistance. Wide-mouth containers are challenging to produce using blow molding due to the difficulty in stabilizing the precision of the mouth. Therefore, we optimized the component shape through repeated prototypes. The three-type, five-layer multi-layer bottle can provide oxidation prevention effects, which can be expected to extend the shelf life when used for food bottles. [Case Overview] ■ Requests - Focus on deformation prevention during high-temperature filling and heat resistance ■ Proposal Points - Selected PP resin considering heat resistance among food-grade resins, and adopted a rib shape for the body as a deformation countermeasure - Proposed a three-type, five-layer multi-layer bottle using EVOH *For more details, please refer to the PDF document or feel free to contact us.
