Bottle Manufacturing
JXPACK’s plastic bottle manufacturing facility integrates advanced injection molding and blow - molding systems, operated by cross - functional process engineers. These experts optimize resin formulations and tooling workflows to deliver precision - molded bottles — balancing high efficiency, cost - effectiveness, and sustainable recyclable material integration.
How Plastic Bottles Are Made
Our facility in guangzhou, a hub for advanced manufacturing, achieves daily output flexibility from 100,000 to 500,000 plastic bottles. Leveraging smart injection - blow molding systems and a cross - skilled team, we serve diverse sectors — beverage, food, cosmetics, and specialty packaging (e.g., medical, personal care).
The production of plastic bottles follows precision - engineered stages: resin compounding (integrating colorants, recycled content, or functional additives), injection molding of preforms, stretch - blow molding for shape formation, and post - processing (edge trimming, surface treatment, or sterilization). Each stage is optimized for speed, cost - efficiency, and material sustainability, with tooling adaptability to meet custom design demands.

How to Make Plastic Bottles Step by Step
#1 Raw Materials for Making Plastic Bottles
The core raw materials for plastic bottle production are resin pellets (e.g., PET, PETG, PP), paired with functional additives — color masterbatch for tinting, UV stabilizers for durability, and recycled content for sustainability. Formulations adapt to end - use needs: food - grade resins meet safety standards, impact - resistant blends integrate toughening agents, and bio - based polymers (e.g., PLA) or rPET enable eco - friendly designs.

#2 Batching & Pre - mixing for Plastic Bottles
Resin pellets (e.g., PET, HDPE) and functional additives (color masterbatch, UV stabilizers) are first dried to remove moisture (critical for clarity and strength). They’re then fed into a loss - in - weight dosing system, which dispenses precise ratios into high - speed mixers.
This pre - mixing stage ensures uniform distribution of additives. Batch size is calibrated to match production volume and mold capacity, while resin moisture content and additive dispersion are tightly controlled — key to avoiding defects like haze or inconsistent performance.
#3 Plastic Resin Melting & Conditioning
Resin pellets (e.g., PET, PP) are fed into a screw - extruder, where staged heating (180–280°C, varying by resin type) and mechanical shear melt them into a uniform fluid. Unlike glass, moisture in pellets is first removed via dehumidification (to avoid bubbles/cracking), while additives (e.g., UV stabilizers) blend uniformly during melting.
Our extrusion lines use smart temperature - control systems, with AI - driven software optimizing melt viscosity for consistent forming — managed remotely by process engineers.
#4 Plastic Bottle Forming Processes
Plastic bottle formation begins with injection - molding preforms: molten resin is injected into cooled molds to create tube - shaped preforms (with built - in threads for caps). These preforms are then sorted and fed into blow - molding systems.
The final shape is achieved through two key methods: Injection Blow Molding (IBM) for wide - mouth containers (e.g., jars, buckets) and Stretch Blow Molding (SBM) for narrow - neck bottles (e.g., beverage, skincare bottles).
Stretch Blow Molding (SBM)
In SBM, preforms are reheated (targeting the body area), then stretched by a rod while air pressure expands them against the mold. This biaxial stretching aligns molecules, enhancing strength and clarity — perfect for PET bottles needing durability and transparency.
#5 Post - Processing for Plastic Bottles
After forming, plastic bottles are first trimmed (laser or mechanical) to remove flash. They then enter a heat - setting tunnel, where gradual temperature cycling (60–180°C, resin - specific) relieves stress from molding/stretching and locks in shape stability.
Key post - processes include:
Surface activation (corona/plasma) for label adhesion Sterilization (UV/hydrogen peroxide for food/medical grades) Leak testing via pressure/vacuum checks
We control these steps to:
- Ensure shape consistency
- Reduce internal stresses
- Boost functional compatibility (printing, sealing)
#6 Plastic Bottle Surface Finishing
Surface finishes on plastic bottles blend branding versatility with functional innovation. Leveraging plastic - specific techniques (digital printing, in - mold labeling, etc.), we deliver treatments for aesthetics, durability, and user experience — backed by advanced equipment and tailored expertise.
