Creating the ideal honey bottle is a complex engineering challenge. The bottle body must possess superior “flex-crack resistance” to withstand repeated squeezing, while the neck must remain completely rigid and dimensionally perfect to form a leak-proof seal with anti-drip silicone valve caps. Traditional manufacturing methods often struggle to balance these two opposing requirements. However, utilizing a máquina de moldeo por soplado y estirado por inyección de una sola etapa provides the ultimate solution. By integrating the entire forming process into one continuous operation, our equipment ensures pristine optical clarity, unmatched neck precision, and massive efficiency gains.
The One-Step Process Flow
Our technology completes the journey from raw resin to finished bottle in four seamless stages, without the preform ever leaving the machine’s controlled environment:
- 1. Inyección: Molten plastic forms the preform. The valve neck is injection-molded to exact tolerances and remains locked in its mold, preventing any future thermal distortion.
- 2. Heat Preservation: The preform’s residual heat is intelligently distributed. This ensures the material is perfectly pliable for the body, while the neck remains cool and solid.
- 3. Moldeo por soplado y estiramiento: The body is biaxially stretched, aligning the polymer chains to give the bottle its highly durable, squeezable “memory.”
- 4. Botella para llevar: The finished honey bottle is automatically ejected, completely scratch-free and ready for filling.

Deep Dive: Equipment Composition & Key Technologies
The perfect squeezable honey bottle relies on five integrated, state-of-the-art technological systems.
1. High-Precision Injection System
Using a servo-driven unit, the injection system forms the preform. We emphasize our patented injection screw and barrel design, meticulously engineered to melt food-grade PET and PP without inducing sheer stress or bubbles, ensuring a flawlessly transparent bottle.
Our Patented Injection Screw guarantees uniform plastic melt.
- Strict temperature control system maintains accuracy within ±1℃.
- Servo-driven dynamics offer fast response and unparalleled repeat precision.
- Preform wall thickness control enables exact axial/radial material distribution for optimal “squeezability.”
2. Sistema de calefacción inteligente
Honey bears and custom shapes require specific wall thickness variations. Our system achieves this through adaptive heating.
- Zoned heating control enables pinpoint temperature profiling across the preform body.
- Non-contact temperature measurement safeguards the preform’s outer surface from damage.
- Adaptive power algorithms self-optimize based on real-time production speeds.
3. Sistema de soplado de estiramiento
- High-speed stretch mechanism operates up to 400mm/s with a positional accuracy of ±0.1mm.
- Independent high-pressure regulating valves ensure pressure fluctuations remain under ±0.05MPa.
- Synchronous control technology perfectly matches the stretch and blow timing.
4. Sistema de moldeo multiestación
We configure the rotary mold stations based on the complexity of your food packaging.
3-Station Mold Structure
Integrates Injection, Stretch Blowing, and Ejection. The go-to setup for standard, high-volume squeezable bottles.

Material Applications & Food Packaging
As a highly adaptable Equipo de soplado de botellas de un solo paso provider, our machines perfectly process the best food-grade plastics:
- MASCOTA: The ideal choice for honey and syrups. It offers spectacular clarity, a strong oxygen barrier, and excellent squeezable flex properties.
- PÁGINAS: Chosen for hot-fill sauces or inverted squeeze bottles requiring high chemical and heat resistance (up to 120℃).
- PETG: Applied in premium, thick-walled cosmetic jars or specialized high-impact food containers.
- ORDENADOR PERSONAL: Used for rigid, reusable drinkware and high-strength baby bottles.
Crucial Integration: Food-Grade Oil-Free Air Compressors
In food packaging, aesthetics and hygiene are inseparable. The most critical, yet often underestimated, component of the ISBM line is the blowing air compressor.
During the stretch blow molding phase, massive volumes of high-pressure air are forced directly into the hot preform, making intimate contact with the interior surface of the honey bottle. If standard industrial compressors are used, microscopic oil vapors and moisture will be blown directly into the bottle. This not only ruins the pristine clarity of the PET, causing it to cloud, but introduces severe food safety contamination.
Furthermore, maintaining the uniform wall thickness required for a bottle to squeeze properly requires absolutely stable air pressure. Ever Power resolves these critical challenges by providing perfectly matched 100% oil-free screw air compressors. Integrated seamlessly with our molding machines, they deliver a sterile, dry, and highly consistent air supply. This ensures your honey bottles are crystal clear, structurally flawless, and strictly compliant with global food safety standards.
Real Feedback from Global Food Packagers
“Leaking honey bottles used to cost us major retail contracts. The anti-drip silicone valves just wouldn’t seal on our older two-step bottles due to neck warping. Ever Power’s machine eliminated this completely. The injection precision on the neck is phenomenal.”
— Packaging Manager, National Honey Brand (New Zealand)
“The flexibility of this equipment is amazing. We use the rapid mold change technology to switch from thick PP sauce bottles to squeezable PET syrup bottles in under an hour. Plus, the energy savings are visible on every monthly utility bill.”
— Operations Director, Condiment Manufacturer (Italy)
“Hygiene is paramount in our facility. Sourcing the machine and the matched oil-free compressor from Ever Power guaranteed a sterile blowing environment. The bottles are flawless, and we easily pass all our stringent food safety audits.”
— Plant Lead, Food Packaging Supplier (Canada)
Preguntas frecuentes (FAQ)
1. How does the machine prevent the valve neck from warping during blowing?
In our one-step process, the neck is formed in the injection mold and securely held by the neck ring throughout the heating and blowing phases. It is never subjected to the thermal stress of a secondary reheating oven, guaranteeing it retains its exact dimensions for leak-proof valve sealing.
2. Can this equipment produce asymmetrical shapes like the classic “Honey Bear”?
Yes. The machine features an advanced zoned heating system that allows for precise thermal profiling. This enables us to blow complex, asymmetrical shapes while maintaining the necessary uniform wall thickness for squeezability.
3. What material provides the best “flex memory” for squeezing?
PET is highly recommended. When biaxially oriented in our ISBM machine, PET develops excellent flex-crack resistance and memory, allowing the bottle to easily return to its original shape after squeezing, while offering superb clarity to display the product.
4. How much energy does this machine save compared to traditional two-step systems?
Because it utilizes the residual heat from the injection process to condition the preform for blowing, the machine eliminates the need for separate preform heating ovens. This typically results in energy savings of around 40%.
5. How fast can we change molds for a different bottle design?
Our equipment utilizes rapid mold change technology. A trained operational team can completely replace the preform and blow molds, load the new parameters, and begin the next production run in 60 minutes or less.
