Technical QC Standards That
Protect Your Production Line
Every batch of 30/25 PET Preforms is inspected across key technical points, not only by appearance. We check wall thickness, neck finish, transparency, material safety, and blow molding performance before shipment.
Uniform Wall Thickness
Consistent Stretch · Stable Bottle ShapeWall thickness deviation is measured at multiple cross-sections using precision gauges. Uniform distribution ensures even biaxial stretch during blow molding, preventing thin spots, stress cracking, and uneven bottle sidewalls.
Stable Neck Finish Dimensions
30/25 Neck Finish · Reliable Cap SealingNeck diameter, thread area, and support ring dimensions are checked against the 30/25 neck specification. Stable neck dimensions help improve screw cap matching, filling line compatibility, and leakage control.
High Optical Transparency
Virgin PET ResinWe use food-grade virgin PET resin as standard to produce clear, bright finished bottles. Transparency and color consistency are checked to meet water and beverage bottle appearance requirements.
Consistent Blow Molding Performance
High Yield RatePreform weight, body length, and IV value (intrinsic viscosity) are controlled within tight tolerances to ensure stable stretch-blow ratios. This reduces bottle deformation, lowers rejection rates, and improves your overall line efficiency.
Food-Grade Material Compliance
SGS CertifiedAll raw materials are verified against FDA 21 CFR, EU 10/2011, and GB 4806 food-contact regulations. SGS material reports are available per batch, covering heavy metal migration, acetaldehyde content, and total migration limits for direct food and beverage contact.
