Wash-Off Label Material
Wash-off label material uses an adhesive engineered to release cleanly from containers in a warm caustic or wash process, so bottles and jars can be recycled or refilled without label residue. It is a key enabler for PET-bottle recycling and returnable-packaging schemes.
Quick answer
Wash-off label material is a paper or film (including rPET) facestock laminated with an adhesive engineered to release cleanly from the container during a warm caustic wash, leaving no residue. It is used on PET beverage bottles and returnable or refillable glass and PET packaging to enable bottle-to-bottle recycling and reuse cycles.

Why choose wash-off label material
Releases cleanly in recycling / wash
The adhesive lifts off in the warm caustic bath, leaving no residue on the container.
Supports PET bottle-to-bottle recycling
Label and adhesive separate from the flake, improving the purity of the recycled PET.
Enables returnable and refillable packaging
Bottles can be de-labelled and relabelled through repeated return-and-refill cycles.
Helps meet EPR and design-for-recycling rules
A recognised route to packaging-recyclability targets in EPR-driven markets.
Typical applications

Wash-off adhesive construction
Best for: Labels that must separate during bottle washing or recycling
Watch-outs: Release depends on wash chemistry, temperature and dwell time; testing required
This page →Recyclable-compatible construction
Best for: Labels designed around a specific recycling stream and container resin
Watch-outs: Compatibility varies by local recycling requirements
Recyclable compatible →Standard permanent acrylic
Best for: Long-term bond on packaging that is not washed or reprocessed
Watch-outs: Adhesive residue and label fragments in wash and recycling lines
Adhesives & liners →Removable adhesive
Best for: Manual peel and promotional labels removed by hand
Watch-outs: Hand removal is not the same as automated wash-off release

Wash-off testing by container type
Send the information in the last column with your sample request so we can propose a construction to test.
| Container type | Typical wash-off question | What to test before bulk order | Information to send |
|---|---|---|---|
| PET bottle | Does the label separate in the hot caustic wash and float off in the flake stream? | Label separation, ink bleed and residue on flakes | Bottle sample, wash temperature and chemistry, ink and varnish details |
| Glass bottle | Does the label release cleanly in the bottle washer for refill? | Release time, paper break-up and residual adhesive on glass | Bottle sample, washer temperature, caustic concentration, cycle time |
| HDPE / PP container | Does the adhesive stay bonded in service but release in reprocessing? | Bond during distribution, then release behaviour in your process | Container sample, surface treatment, filling and storage conditions |
| Returnable / refillable packs | How many cycles must the pack survive before relabelling? | Repeat wash cycles and cumulative residue | Cycle count, wash line details, target label life |
When this material may not be the best fit
Wash-off adhesive is not the right choice where the label must hold permanently through wet distribution, long outdoor service or aggressive cleaning during use. Bond strength is deliberately designed to release under defined wash conditions.
Performance depends on the container, ink, varnish, application conditions and the actual wash process. Test with your own bottle and wash line before bulk order rather than relying on a general specification.
Adhesive & liner options
Wash-off adhesive can be paired with paper, film or rPET facestocks on glassine, PET or CCK liner. Tell us the container, wash temperature and caustic concentration and we will match the construction.

To check availability, sample options and lead time, send us your application, label size, roll width, facestock, adhesive, liner, printing method and estimated order volume. Our team will recommend a suitable construction and confirm whether a sample roll or trial order is available.
Selection depends on container, adhesive, liner, printing method and service environment. We confirm every construction against your own substrate and line conditions before bulk production.
Frequently asked questions
What is wash-off label material?
Wash-off label material combines a paper or film facestock, including rPET options, with an adhesive engineered to release cleanly from the container in a warm caustic wash. The label and adhesive separate from the bottle instead of shredding into the recycling stream, which is what allows bottle-to-bottle recycling and returnable-bottle reuse to work.
It is used on PET beverage bottles heading into closed-loop recycling, and on returnable and refillable glass or PET packaging for breweries, dairies and water suppliers.
Define the wash conditions you must meet — temperature, caustic concentration, dwell time — plus service conditions before washing, such as fridge condensation, ice water and abrasion in transit. Then match facestock, adhesive and print so the label survives use but leaves no residue. Wash performance is line-specific — confirm with sample testing against your own process.
What is a wash-off label?
A label whose adhesive releases cleanly from the container during a warm caustic or wash process, so the pack can be recycled or refilled without residue.
How does wash-off adhesive help recycling?
It lets the label and adhesive separate from PET or glass in the recycling wash, improving the purity of the recycled material.
Are wash-off labels EPR compliant?
They support design-for-recycling and EPR goals; exact compliance depends on the facestock and recycling stream — we can advise per market.
Can wash-off be used for returnable bottles?
Yes, it is widely used for returnable and refillable bottle schemes where labels must come off cleanly for reuse.
What wash temperature does wash-off adhesive release at?
Wash-off adhesive is engineered to release in a warm caustic wash typical of PET bottle-recycling and returnable-bottle wash lines; the exact release temperature and caustic concentration are confirmed on the datasheet, since they are tuned to your specific wash process and container material.
Which print methods work on wash-off label constructions?
Wash-off adhesive can be paired with paper, film or rPET facestocks, so it supports flexo, offset, UV inkjet and digital printing just like our standard label materials — the adhesive layer does not limit which print method you choose.
Can I get a free sample of wash-off label material?
Yes, request a free sample paired with your preferred facestock, along with the datasheet, so you can trial the wash-off release in your own wash line or with your recycler before committing to a production order.
What is the minimum order quantity (MOQ)?
Stocked grades start from 1 jumbo roll. Custom constructions or coatings typically start from 3,000–5,000 square meters, depending on complexity.
What adhesive and liner options are available?
Permanent, removable, deep-freeze, high-tack or wash-off adhesive (water-based or hot-melt), on white glassine, PET or CCK/kraft liner — matched to your surface and environment.
