Why PETG shrink film is recyclable and how it be recycled

PETG shrink film, made from Polyethylene Terephthalate Glycol, is widely used in packaging due to its strength, clarity, and excellent shrinkage properties. But what makes PETG shrink film recyclable — and how exactly is it recycled?

Why PETG Shrink Film Is Recyclable

▶ Thermoplastic Composition
PETG is a type of thermoplastic, meaning it can be melted and reshaped multiple times without degrading its chemical structure. This makes it ideal for recycling.

▶ Non-toxic and Stable
PETG does not release harmful substances when processed under normal conditions, unlike certain PVC shrink films. Its stability ensures safe handling during recycling.

▶ High Clarity and Purity
Because PETG film is often made without pigments or additives, it maintains a cleaner recycling stream — especially when separated from other plastics like PVC or PS.

▶ Compatible with Existing PET Recycling Systems
PETG can be recycled in facilities that process PET, although it may need to be separated if purity is critical for high-grade PET recycling.

How PETG Shrink Film Is Recycled

The recycling process for PETG shrink film typically involves the following steps:

1. Collection and Sorting

PETG shrink film waste is collected from packaging waste streams.

Films are sorted manually or with optical sorters to separate PETG from other materials like PVC, which contaminates the PET stream.

2. Shredding

The sorted PETG shrink film is shredded into small flakes to increase surface area and make further processing more efficient.

3. Washing

The flakes are washed with water and sometimes mild detergents to remove labels, adhesives, and contaminants such as inks or food residues.

4. Separation

A density separation process may be used to remove non-PETG particles.

Since PETG is heavier than water, it sinks — helping to isolate it from lighter plastic contaminants.

5. Drying and Melting

Cleaned PETG flakes are dried and then melted through an extruder.

The molten PETG is formed into pellets or sheets for reuse.

6. Reuse

Recycled PETG is used to make various products:

New shrink films

Rigid packaging (e.g., clamshells)

Thermoformed trays

3D printing filaments

Tips for Better PETG Recycling

 •Avoid mixing with PVC: Always label PETG clearly to avoid contamination.

 •Use minimal ink or adhesive: This reduces processing time and contamination risk.

 •Work with specialized recyclers: Some facilities focus on PETG and can ensure high recovery rates.

PETG shrink film is recyclable because it is a clean, non-toxic thermoplastic compatible with PET recycling streams. With proper sorting, cleaning, and reprocessing, PETG can be transformed into valuable secondary products — supporting sustainability in the packaging industry. We are a professional shrink sleeve film manufacturer, providing shrink films of various materials, including PETG, CPET shrink films, etc.
