PET Preforms of 380 Gms and 400 Gms for NRB Water Bottles: Quality, Procedure, Safety, and Raw Materials
We specialize in manufacturing high-quality PET (Polyethylene Terephthalate) preforms of 380 gm and 400 gm, designed explicitly for the production of NRB (Non-Returnable Bottles) water bottles with a capacity of 5 gallons. Ensuring quality, safety, and compliance at every step, these preforms are ideal for creating durable, food-grade water containers.
Quality Standards
1. Material Properties
PET preforms are made using premium-grade PET resin, characterized by its lightweight nature, robustness, and high optical clarity. These features ensure that the finished 5-gallon water bottles are visually appealing and capable of withstanding various handling and transportation conditions without deformation or damage.
2. Dimensional Accuracy
The production process leverages advanced injection moulding technology and precision-engineered molds, resulting in consistent wall thickness and a uniform shape. This dimensional accuracy enhances the bottles’ structural integrity and facilitates compatibility with capping and filling systems.
3. Certifications and Compliance
All preforms are manufactured in compliance with international food safety and quality standards. This ensures bottles are safe for human consumption and meet the requirements of regulatory authorities.
Manufacturing Procedure
Raw Material Preparation
PET granules, sourced from reputable suppliers, undergo thorough drying to eliminate moisture content. This step is critical to prevent defects like cloudiness, cracking, or brittleness during the injection moulding process.
Injection Moulding
The dried PET granules are melted at controlled temperatures and injected into custom molds under high pressure. The precision of this process ensures that the preforms achieve their designated shape, weight, and clarity. Cooling systems solidify the preforms, locking in their durability and transparency.
Quality Control and Testing
Rigorous quality assurance measures are implemented, including:
Weight Consistency
Wall Thickness Uniformity
Stress Testing
Fit for Human Consumption
Non-Toxic and Food-Safe
PET is an inert material that does not leach harmful substances into water, making it a trusted choice for food and beverage packaging.
Hygienic Manufacturing
Production occurs in clean-room facilities, ensuring that the preforms are free from contamination by dust, microbes, or other environmental factors.
Custom Designs
Tailored PET bottles to meet your unique branding needs.
Barrier Properties
PET preforms provide excellent resistance against oxygen and other external contaminants. This barrier protection maintains the purity and taste of bottled water over extended storage periods.
