Total cost of ownership
Lower total cost of ownership with right-sized rPET blow molding configuration.
Selecting the correct cavity count and automation level — from 2-cavity semi-automatic to 6-cavity fully automatic — directly drives energy cost, mold investment, and per-bottle overhead for rPET packaging projects.
Output range
RFQ-definedBPH
Capacity depends on cavity count, bottle type, rPET content ratio, and automation level — confirmed by bottle samples and production conditions during FAT.
Wall thickness control
Uniformdistribution
rPET preform design and stretch-blow process parameters are verified at mold temperature, stretch rod alignment, and blow pressure stages during acceptance testing.

Commissioning Support PlanFrom preform design to bottle discharge — the rPET packaging decision flow
The rPET packaging solution spans preform engineering, mold development, blow molding machine selection, bottle sample review, and lightweighting optimization — delivered as a turn-key package covering 2-cavity to 6-cavity configurations for circular economy beverage packaging.
Label path clarity
Roll feed, peel plate, and applicator position are arranged so operators can see and correct the web path quickly.
Bottle transport stability
Guides, side belts, and conveyor timing keep the label target steady through application.
Operator-friendly access
Roll changes, sensor adjustment, and applicator access stay within the operator's working zone.
Engineering advantages that protect rPET bottle quality.
Label transfer
Accurate placement comes from trigger timing and applicator geometry.
Changeover
Fast service access keeps roll changes and cleaning practical.
Core process — from rPET preform design to blow molding and bottle review.
The rPET packaging process spans three stages: preform design and mold engineering, stretch-blow molding with single-stage or two-stage processing, and bottle sample review with lightweighting optimization. Upstream line control can be aligned with a PET bottle blowing machine , while downstream traceability and pack-out often connect to a laser coding machine and a shrink wrapping machine .
Label unwind
- Roll feed stays stable before the label event.
- Peel plate and feed path keep the liner readable.
- Label stock is delivered cleanly so the adhesive face reaches the applicator without drift.
Label application
- Trigger timing aligns the label event to the bottle body.
- Applicator pressure and conveyor speed are tuned together for consistent placement.
- Labels land on the intended zone through pressure-sensitive contact and controlled wipe-down pressure.
Bottle exit
- Bottle exits with visible placement and enough access for inspection.
- Inspection access stays open for quick operator checks and cleaning.
- Change parts are set by bottle family and label roll width.

Label waste & uptime
Reduce missed labels, liner breaks, and reject loops at the pressure-sensitive label station.
Liner and label waste
Controlled unwind tension, peel-plate transfer, and wipe-down contact reduce missed labels, skewed placement, and liner breaks.
Reel-change uptime
Roll access, web-path visibility, and saved recipes shorten recovery after label-roll change or bottle-family changeover.
RPET Blow Molding Machine In Action
Acceptance should prove more than throughput: the adhesive labeler has to show stable web tracking, square presentation on the bottle, readable sensor response, and repeatable restart behavior after reel and size changes.

FAQ — rPET packaging design and blow molding
What is the difference between rPET and virgin PET in blow molding?
rPET requires a barrier screw with venting capability to reduce drying energy consumption, and the processing temperature window is narrower. Single-stage processing can avoid reheating and lower carbon footprint. Our solution supports rPET-dedicated screw configurations.
Can existing blow molding machines process rPET?
It depends on the existing screw type and mold condition. We provide an assessment service to confirm whether screw upgrades, temperature control adjustments, or mold replacement are needed. Typical configurations can support 25-50% rPET blending.
Do you support 100% rPET?
Project-dependent. 100% rPET places higher demands on screw venting, mold temperature control, and preform design. We typically start from 25% and gradually increase. Regulatory requirements such as the 25% rPET mandate in Taiwan serve as a baseline.
What do I need to provide for preform design?
2D engineering drawings including neck thread specifications, 3D models in STEP or IGES format, or sample bottles. We handle everything from design review to mold machining in one integrated process.
What does the turn-key solution include?
Preform design, mold development, blow molding machine, auxiliary equipment, factory layout, installation and commissioning, and operator training — covering the full delivery from rPET preform engineering to high-speed bottle production.
