PET Chips Oil Bottle Grade

1. What are Oil Bottle Grade Polyester Chips?

Oil bottle grade polyester chips are a high-quality polyethylene terephthalate (PET) material specifically designed for edible oil packaging. Compared to CSD bottle grade PET, it focuses more on impermeability, oil resistance, and long-term stability, ensuring the quality of edible oil remains within its shelf life.

2. What are the advantages of using PET chips oil bottle grade?

Excellent oil resistance: PET resin has extremely strong chemical resistance to edible oils and lubricants and will not degrade or absorb odors.

Strong barrier properties: Effectively blocks oxygen, moisture, and odors, preventing oxygen from entering and causing oil oxidation and rancidity.

High transparency and gloss: Compared to HDPE, PET has better transparency, showcasing the color of the oil.

Lightweight and impact-resistant: Reduces transportation costs.

Food safety: Meets international food contact material standards.

Recyclability: Environmentally sustainable.

3. What is the typical IV value of oil bottle grade polyester chips?

The IV value of polyester chips used in oil bottles is generally higher than that of PET for water bottles, but lower than that of PET for CSD bottles, typically 0.80-0.85. Our company can provide PET IV 0.83 (WK-821, YS-Y01, BG802), PET IV 0.84 (TH102C), and IV 0.85 (CZ-318) for oil bottles production.

4. What types of bottles can oil bottle-grade polyester chips be used for?

Edible oil bottles, automotive fuel bottles, detergent bottles, and cosmetic bottles, etc.

Bottle capacities are typically from 250 ml to 5 liters, with 1 liter and 5 liters being the most common.

5. What are the key performance indicators of oil bottle-grade PET?

PET chips oil bottle grade must meet strict specifications to ensure durability and safety. Typical properties include:   

Intrinsic Viscosity (IV): 0.80–0.85 dL/g

Acetaldehyde Content: ≤1 ppm

Moisture Content: ≤50 ppm

Color (L-value): High brightness for clarity

Melting Point: 245–252°C

Density: 1.40 g/cm³

6. Why is oxygen barrier properties particularly important for PET edible oil bottle grade?

Oxygen is the main factor causing edible oils to oxidize and become rancid, developing a pungent odor. The oxygen barrier properties of PET oil bottles directly determine the shelf life of cooking oils.

General requirements:

Grade A edible oils should have a shelf life of 18-24 months.

Specialty oils (such as olive oil and camellia oil) may require bottle-grade polyester chips with higher barrier properties.
