As the foundational semi-finished component of countless plastic cosmetic and daily-use containers, high-quality PET bottle preforms determine the final appearance, pressure-resistance performance and sealing stability of your finished packaging. Chenmei Packaging Technology Co., Ltd. supplies a comprehensive range of injection-molded PET preforms in multiple neck finishes, wall-thickness specifications and blank weights, ready for your subsequent blow-molding production.
Every batch of pre-made blanks goes through strict dimensional inspection, visual defect screening and material-hardness sampling testing to rule out scratches, bubbles, uneven wall thickness and injection defects. We support customized injection molding services according to your 2D-3D technical drawings and finished-bottle development requirements.
We offer you various high-quality Lotion Bottle Preforms and Spray Bottle Preforms of different specifications. Please feel free to come and inquire!
Uniform wall-thickness distribution across preform bodies is essential for error-free blow-molding. Our quality-control team carries out multi-point thickness measurement for each production run. Precise thread-opening dimension ensures perfect matching with standard screw caps, pump dispensers and spray accessories, effectively preventing fitting failure, liquid leakage and finished-bottle waste during your downstream processing.
All of our PET bottle preforms are manufactured from virgin, odor-free PET resin that meets international food-contact safety standards. Third-party material safety reports can be provided for your overseas product filing and customs clearance. Recycled raw-materials with unknown chemical risks are firmly rejected during incoming-material inspection to protect your skincare and beverage formulas from contamination.
Common-spec stock pre-blanks are kept in inventory for short-lead-time small-batch orders. Our customization services cover Pantone color tinting, special-neck-thread development, heavy-wall thickened preform designs and exclusive mould-opening for large-volume buyers. You are free to develop diversified finished-container styles including round bottles, flat-shoulder containers and shaped cosmetic bottles from our preform blanks.
Our PET pre-moulded blanks can be blow-molded into travel-size cosmetic packaging, household liquid-storage bottles, beverage containers, cleaning-product bottles and hotel disposable packaging solutions, well-suited for skincare brands, daily-chemical factories and packaging blow-molding processors.
These PET preform blanks are semi-finished products that require secondary heating and blow-molding procedures to form finished hollow bottles. Avoid over-stretching bottle bodies during heating-blowing, otherwise thin-wall weak points and cracking risks will appear. After blow-molding, inspect finished containers for air-tightness before liquid filling.
Keep unused PET preforms stored in cool, dry, dust-free indoor conditions. Long-time exposure under high-temperature environments or direct sunlight will trigger material aging, deformation and yellowing of pre-blank bodies. Seal leftover preform stocks well to prevent dust and particle pollution on thread sections.
PET blanks are designed for one-time blow-molding forming. Once heated and stretched into finished bottles, they cannot be reheated and reshaped again. Please separate qualified and defective preform products before sending them to your blow-molding workshop to avoid production interruptions.
Thin side-walls, bottle-body warping or neck-thread distortion after blow-molding are generally caused by uneven heating temperature or inconsistent preform wall-thickness. Our technical team can provide remote-process guidance to help you adjust your blow-molding machine parameters.
We operate our own-in-house injection-molding workshops and complete preform production lines, which enables us to control product quality from the earliest raw-material injection stage. Our technical engineers can optimize pre-blank structures to match your blow-molding equipment, lowering finished-product defect rates for your downstream manufacturing.
We deliver stable stock supply for standard-size PET pre-blanks, while rush-order injection-molding schedules are available for urgent-demand clients. Multiple flexible cooperation modes are supported, from off-the-shelf preform purchasing, small-batch sample injection to large-scale exclusive-mold development projects.
