Blow Molding Machine for Food Containers | Chen Way
Continuous extrusion and semi-automatic stretch blow molding machines for food containers such as edible oil jerry cans, sauce bottles, jugs and storage jars.
Food Containers
Blow molding is widely used in the production of food containers, including beverage bottles, dairy containers, sauce bottles, and opaque containers such as edible oil drums. Common raw materials include HDPE and PP, which provide excellent impact resistance and chemical stability.
To meet food preservation requirements, many blow-molded containers use multi-layer co-extrusion technology, incorporating oxygen-barrier materials such as EVOH to extend product shelf life. Furthermore, these containers can be engineered with specialized shapes, ergonomic grips, and leak-proof caps to enhance user convenience and brand recognition.
Food-grade blow-molded containers must adhere to stringent hygiene and safety standards. The manufacturing process requires the use of non-toxic, food-contact-approved plastics, often paired with equipment such as automatic leak testers to ensure consistent quality and integrity.
Over 35 years of expertise in blow molding equipment make us the preferred choice for long-term partners.
Machine Routes for Bottles, Jugs and Food Storage Jars
Opaque food containers such as edible oil jerry cans, sauce bottles and milk jugs are usually HDPE or PP and run on continuous extrusion machines sized by container volume, from small bottles to 10-30 L jerry cans. Three-layer edible oil jerry cans are an established application of Chen Way's co-extrusion models. Clear storage jars, goblets and kettles follow a different route on the semi-automatic stretch blow molding machine, which reheats preforms and stretches them during blowing.
Food-contact approval of the resin and hygiene requirements for the production area remain the container producer's responsibility, so state them in the inquiry with any barrier-layer or leak-testing needs. Compare the 10-30 L jerry can machine with the semi-automatic stretch blow molding machine to see which route fits, then send container volume, resin and output targets for a proposal.
