What are the advantages of polyester chips in the production of bottle packaging?
High strength and high toughness. PET material has excellent tensile and impact strength. Bottles made through biaxial blow molding can have very thin walls, yet can withstand the internal pressure of carbonated beverages and impacts during transportation, making them less prone to breakage and ensuring high safety.
Excellent transparency and gloss. Virgin food-grade PET chips can produce crystal-clear bottles that perfectly showcase the color and texture of beverages, cooking oils, and other contents, greatly enhancing the product’s visual appeal on the shelf.
Excellent chemical stability and inertness. PET resin exhibits high stability against common food components such as water, acids, oils, and alcohol at room temperature, without undergoing chemical reactions, ensuring the purity of the contents’ flavor.
Lightweight and convenient for transportation. PET has a moderate density, making bottles much lighter than glass bottles, significantly reducing packaging weight and thus reducing raw material usage and energy consumption and costs during long-distance transportation.
Strict food safety standards. The production of food-grade PET chips for bottles must comply with the strictest global food safety regulations. During production, strict control over raw material purity, catalyst residue, and polymerization processes ensures that the content of potential migrating substances such as heavy metals and acetaldehyde is extremely low when in contact with food, far below legal limits, making it safe and harmless.
High plasticity and high processing efficiency. PET chips have a well-defined melting point and melt flowability, resulting in extremely high production efficiency.
FAQs PET Resin Bottle Grade
1. What are PET resin bottle grade?
PET resin bottle grade are a high-purity, high-performance plastic raw material specifically designed for manufacturing various bottle packaging. They are typically white, cylindrical or flattened granules. These granules are usually first made into PET preforms, and then further processed through heating, stretching, blow molding, etc., to create the mineral water bottles, cola bottles, edible oil bottles, juice bottles commonly found in our daily lives.
2. What is the difference between bottle-grade polyester chips and fiber-grade polyester chips?
They are both polyethylene terephthalate, but they differ significantly in production processes, molecular structure control, and basic properties. PET Chips used to manufacture polyester fibers focus on spinnability and softness. Bottle-grade polyester chips have extremely stringent requirements regarding transparency, strength, purity, gas barrier properties, and food safety than fiber-grade PET chips.
3. Are bottle grade polyester chips universal?
No. Depending on the application, there are sub-types:
General-purpose type (water bottle type): Used for room-temperature mineral water bottles and purified water bottles.
Carbonated beverage type: Commonly used for packaging carbonated beverages, such as cola and soda.
Hot-fill type: Used for beverages such as tea and juice that require filling at temperatures above 85℃. These polyester chips need higher heat resistance.
Edible oil type: Has special requirements for light protection and oxygen barrier properties.
4. Can PET plastic bottles be used to hold hot water?
General-purpose PET beverage bottles are not heat-resistant. Hot-fill beverage bottles are specially designed. High temperatures may cause bottle deformation and accelerate the release of trace substances. Therefore, they are not recommended for holding boiling water or hot drinks.
5. Can PET plastic bottles be reused?
They are designed for single use and long-term reuse is not recommended. Repeated washing and wear can easily breed bacteria. In addition, long-term use may cause material aging and release harmful substances.
6. What are other applications of PET chips bottle grade?
PET bottle chips are also popular for packaging salad dressings, cooking oils, peanut butter, shampoos, hand sanitizers, mouthwashes and other personal care products.
Special bottle grade PET resin can be used in the processing of takeaway containers and food trays that can be heated in the oven or microwave.
