Why and How can PET materials Outperform PVC
Picking the best material for packaging liquids can greatly affect how smoothly a production line runs and how well a brand performs. For a long time, people in the industry argued over PET and PVC. Yet, with a growing focus on eco-friendliness and safety for food, PET has emerged as the clear leader in the packaging field.
Although these two materials might seem alike at first glance, their actual behavior in factories and their effects on the planet differ sharply. For businesses such as BJY, moving to PET is more than a passing fad; it forms the basis of today’s fast-paced bottling processes.
Why Is PET the Superior Choice for Liquid Packaging?
If you stroll through a typical store today, you’ll notice that nearly all transparent bottles, whether for spring water or fizzy drinks, use PET. PVC was once widespread, but it has mostly faded from use for a few key reasons that matter to both buyers and makers.
Superior Safety and Food Grade Standards
PET comes without BPA by nature, and it avoids the phthalate additives that make PVC pliable yet pose risks to health. For any company dealing in drinks or edibles, PET serves as a reliable option that complies with tough worldwide health rules effortlessly.
High Transparency and Professional Appearance
That’s why upscale water labels prefer PET so much. It offers a sparkling, glass-like shine that makes the contents appear pure and inviting. In contrast, PVC often shows a faint blue or yellow hue, particularly after processing, which fails to deliver that upscale feel.
Excellent Recyclability and Environmental Sustainability
This point stands out the most. PET ranks as the top recycled plastic globally. After use, a PET bottle can be shredded and reformed into a new one (rPET). On the other hand, PVC proves difficult to recycle since its chlorine content harms the machinery involved.
Understanding that PET offers clear advantages is just part of the equation. To truly gain these perks, you must have suitable equipment to form the plastic into an ideal bottle. Here, BJY’s skills in multi-cavity injection molds prove essential, especially for those with robust operations.
What High-Efficiency Solutions Does BJY Provide for PET Preform Injection?
Creating a PET bottle starts with a top-notch preform. If the preform lacks quality, the final bottle will suffer too. Foshan Baijinyi Co., Ltd. (hereinafter referred to as “BJY”) has dedicated years to refining the tools that power the busiest injection systems, making sure each run stays quick and accurate.
72 Cavities Injection Machine Applicable to Husky
The 72 cavities mold for Husky Injection Machines excels in large-scale output. It withstands the high pressure and warmth from a Husky setup, which many consider the benchmark in this sector. Producing 72 flawless preforms in mere seconds is challenging, but this mold handles it with ease.
Precision Control and Tight Tolerances
Handling numerous cavities demands uniformity above all. BJY employs premium steel and advanced CNC machining to maintain narrow tolerances. We’re discussing accuracy within ±0.02mm for the neck area. If the neck falls short, the cap won’t fit properly, leading to spills and lost goods.
Optimized Cooling for Faster Cycles
Efficiency equals profit. The quicker a preform cools, the faster you can remove it and begin again. BJY’s built-in cooling paths extract heat rapidly and uniformly. As a result, preforms avoid distortion, and the line keeps pace without the mold getting too hot.
After preparing those preforms, they must expand into complete bottles. This shift from a compact tube-like form to a full container calls for another level of accuracy, particularly in setups like cold-fill lines that demand specific features.
Advantages of BJY Cold Filling and Blowing Bottle Machine
Cold filling helps keep the flavor and vitamins in delicate beverages intact, but it requires bottles with particular strength. The mold must produce a container sturdy enough to hold shape independently, unlike the firmer hot-fill versions.
Exceptional Thermal Conductivity and Rapid Cooling
Because cold-fill bottles don’t face 85°C heat, the emphasis lies on pace and sharpness. Aluminum’s strong heat conduction allows the PET to solidify quickly against the mold surfaces. Consequently, this preserves the see-through quality and avoids any haze from prolonged warmth.
Extended Service Life and Reliability
Despite being aluminum, these molds endure well. BJY adds a unique coating to resist damage. They’re crafted to last through countless runs. Such dependability lets managers rest easy, free from worries about sudden failures or pauses for mold changes.
At times, the focus isn’t solely on the machine type but on the exact bottle volume that shapes a batch. A common size like 555ml needs a mold suited for rapid spinning while ensuring the base appears neat and polished.
PET Blowing Mold for Krones Cold Filled Blow Molding Machine
Take, for instance, the cold filling and blow molding machine suitable for the Krones brand.The PET blowing mold for Krones is tailored for such equipment. Krones machines operate swiftly and cleverly, so the molds must match that capability.
Why Choose the 555ml Blow Molding Mold for Aseptic Lines?
The 555ml capacity hits a nice balance for various drink makers; it’s slightly over the usual 500ml, offering added worth to shoppers. However, forming them quickly on a sterile line demands a mold that manages stress without issues.
555ml Blow Molding Mold Designed for High-Speed Rotary Machines
The 555ml blow molding mold powers through on fast rotary systems. These can reach up to 55,000 bottles hourly. At such velocity, a small flaw in the design might waste thousands of units in one shift alone.
Sandblasted Bottom for Smooth Demolding
BJY applies a smart technique by sandblasting the mold’s base. It may seem basic, but it prevents the warm PET from adhering to the bottom. This easy release boosts machine speed, as it avoids struggles in extraction. Moreover, it results in a tidy base appearance.
Versatile Application for Various Beverages
From plain water to fruit juices or mild fizzy options, this mold adapts well. It creates a stable, solid bottle that moves steadily along belts, preventing falls or blockages in the packing process.
Ultimately, excellent molds represent only one piece of the puzzle. True worth arises from the experts supporting the gear. In this field, where tiny adjustments can spell triumph or trouble, a knowledgeable ally proves crucial.
How Does BJY Ensure Professional Support and Services?
BJY goes beyond simply delivering metal and vanishing. Their staff, located in Foshan’s bustling manufacturing area in China, recognizes that each plant has unique traits and hurdles.
One-Stop Professional Customization Services
No two lines are identical. BJY provides complete tailoring, starting from basic bottle sketches to recreating outdated components unsupported by prior suppliers. They even assist with equipment shifts; if you aim to adapt your setup for a new form, they manage the entire technical side.
Advanced Inspection and Quality Control
Quality means more than words; it’s gauged in tiny units. BJY relies on elite devices like Zeiss CMM (Coordinate Measuring Machines) and Keyence vision tools. They inspect each mold to confirm it matches the specs precisely. If anything deviates slightly, it stays behind.
Global Compatibility and Proven Expertise
No matter if you use Sidel, Krones, KHS, or Husky, BJY grasps these systems inside out. They’ve partnered with more than 100 firms across the globe, supplying components and molds that match originals, all at a fairer cost.

FAQ
Q1: Can I use BJY molds on my existing Sidel or Krones machines?
A: Absolutely. BJY specializes in making molds and spare parts that are fully compatible with major international brands like Sidel, Krones, and KHS. They design them to fit perfectly without needing major modifications to your current setup.
Q2: Why is aluminum used for blow molds instead of steel?
A: Aluminum (like the A6061 alloy BJY uses) is much better at conducting heat than steel. This means the bottle cools down faster inside the mold, which lets you run the machine at higher speeds and improves the clarity of the PET plastic.
Q3: Does BJY help with bottle design or just mold making?
A: They do both. If you have a rough idea for a new bottle shape, their engineering team can create the 3D designs, perform stress tests to make sure the bottle is strong enough, and then build the molds to produce it. It’s a full “turnkey” service.
