3. ASB-12M-2INJ + Airless Pump Double Layer Container
- ASB-12M-2INJ : 1-Step Double Layer Injection Stretch Blow Molding
- Type : 300ml Airless Pump
- Weight : 28.5 grams (PET : 22.8 grams + PP : 5.7 grams)
- Output : 410 bph
- Application : Liquids requiring no, or minimal contact with headspace air after initial opening.
ASB’s patented Double Layer molding process enables containers to be molded with an inner and outer layer in the body and/or neck section in a variety of thicknesses, configurations, molding order, or resins as required to provide additional flexibility and value to the molded product.
The ASB-12M-2INJ is based on the company’s best-selling ASB-12M model, reengineered with twin injection units and a six-station rotary table that comprise two separate injection and cooling stations. These additions make it possible to dramatically enhance either visual or physical properties using various materials for inner or outer layers.
By adding two sets of lip-plate assembly and a replacement hot runner, mold sets manufactured for standard molding on ASB-12M machines can also be installed and operated, adding flexibility and backward compatibility.
Applications are wide and varied, a few examples include;
Air-Less Pump Container
(as demonstrated at K 2022)
The bottle is designed such that, as the contents are dispensed by a pump-spray that prevents air re-entering the bottle, the inner layer of polypropylene resin is allowed to delaminate from the outer PET layer and collapse with the product. As a result, virtually no headspace develops inside the bottle making it suitable for any liquid products that need protection from air after initial opening of the container.
Ecological Container Using Recycled Flake PET as Outer Layer.
Current production of food grade containers using recycled PET may be limited in many countries due to food safety regulations. This container is molded with an inner layer of virgin PET while the outer layer comprising of up to 70% of the container’s body weight and that never contacts the filled product, can be molded using almost any quality of recycled flake PET.
Moisture Barrier Container
Polypropylene has higher moisture barrier characteristics compared to PET. Either the inner or outer layer, can be enhanced for mascara and other cosmetic containers where the contents require careful protection against moisture loss.
Glass-Like Thick Base Container
The process can be used to fully simulate visually stunning, glass-like containers for premium quality cosmetics. The complex eye-catching colors and extra thick wall and base are available either in bottles or jars.
Unique Design Containers
Integrated stripes, view-stripes, internal ribs, gradation etc.
Additional decorative features such as integrated stripes, internal ribs or gradation etc. can be added to the container design for maximum marketing impact or special functionality.
The great flexibility of the molding method offers untold possibilities and ASB will continue to develop the process and hardware including various capacity machine models according to the requirements and feedback of the market.
