The Problem

Most disposable cups are not as recyclable as they look.

A standard paper cup is coated on the inside with a thin layer of polyethylene (PE) plastic. This PE film makes the cup waterproof — but it also makes the cup nearly impossible to recycle in conventional paper streams. The plastic and paper fibres fuse during manufacturing, requiring specialist separation facilities that most markets simply do not have.

The result: the vast majority of the estimated 500 billion single-use cups produced each year end up in landfill, where the PE layer prevents the paper from biodegrading for decades. Aqueous and PLA coatings were developed specifically to solve this problem.

Why aqueous coating is the future of paper cups

Water-based barrier coating replaces the PE plastic film with a thin dispersion of polymers that bonds directly to the paper fibre — no separate plastic layer, no contamination of the recycling stream.

Aqueous water-based coated paper cups — recyclable and home compostable

What makes aqueous coating different

Water-based, not plastic-based
The barrier is formed by a water-dispersed polymer that integrates with the paper fibre as it dries. There is no separate plastic film to separate during recycling.
Recyclable and repulpable
Accepted by standard paper recycling facilities. The coating disperses during the repulping process, allowing the paper fibres to be recovered and reused.
Home compostable
Unlike PLA, which requires industrial composting conditions (60 °C+), aqueous-coated cups biodegrade under natural soil conditions — no specialist facility required.
Microwaveable and heat-safe
The absence of plastic components means aqueous-coated cups are safe for microwave use, expanding their application to soups, noodles, and reheated meals.
Full custom printing compatible
All standard flexographic inks adhere to aqueous-coated paperboard. Custom branding and full-colour artwork are available from 30,000 pcs per size.

Second Option

PLA: plant-based and industrially compostable

PLA (Poly-lactic Acid) is a new-generation bio-based material derived from renewable plant resources — corn starch and cassava roots. Through saccharification and fermentation, starch is converted into lactic acid, then polymerised into PLA. Under specific conditions, microorganisms in nature can completely degrade PLA into carbon dioxide and water, leaving no toxic residue.

PLA-coated compostable hot paper cups — plant-based inner lining
Hot Cups

PLA-lined paper cups

Standard paper cups with the PE inner film replaced by a PLA bioplastic lining. The paper structure remains unchanged — only the barrier layer is plant-based. Suitable for hot and cold beverages, and certified industrially compostable under EN 13432 / ASTM D6400.

  • Inner lining derived from corn starch
  • Industrially compostable — ~12 weeks at 60 °C+
  • Available in single wall, double wall, and ripple wall
  • Full flexographic custom printing available
PLA clear cold cups — fully compostable transparent cups made from corn starch
Cold Cups

PLA clear cold cups

Fully transparent cups thermoformed entirely from PLA resin — not just coated. The entire cup body is made from plant-based material, making them 100% plastic-free and industrially compostable. Ideal for cold drinks, bubble tea, smoothies, and iced beverages where cup clarity matters.

  • Entire cup body made from PLA — no plastic components
  • Crystal-clear appearance, comparable to PET
  • Industrially compostable — completely biodegradable
  • Available with dome lids and flat lids

Disposal note: PLA products require industrial composting conditions (above 60 °C) to biodegrade within the certified timeframe. They are not suitable for home composting or standard paper/plastic recycling streams. We recommend clear on-cup labelling to guide correct disposal in your market.

FAQ

Common questions about eco coatings

Are aqueous-coated paper cups truly biodegradable?
Yes. Under natural burial conditions, aqueous-coated cups begin visibly breaking down within 85 days and fully degrade by around 245 days. This contrasts sharply with PE-lined cups, which remain structurally intact even after 245 days in the same conditions. The water-based barrier bonds directly to paper fibres without a separate plastic film, allowing natural microbial decomposition.
What is the difference between aqueous coating and PLA coating?
Both are plastic-free alternatives to PE lining. Aqueous (water-based) coating uses a thin polymer dispersion that integrates into the paper fibre, making cups recyclable, repulpable, and home-compostable. PLA coating is derived from corn starch and is industrially compostable (typically 12 weeks at 60 °C+), but it does not degrade reliably at home or in standard recycling streams. For markets without industrial composting infrastructure, aqueous coating is generally the more practical choice.
Can aqueous-coated cups be recycled in standard paper recycling?
Yes. Because the coating is water-based and integrates with the paper fibre rather than forming a separate plastic layer, aqueous-coated cups are accepted by most paper recycling facilities and can be repulped in standard processes. PE-lined cups require specialist facilities that separate the plastic film from the paper.
How much does switching to aqueous coating affect the carbon footprint?
Based on a lifecycle analysis aligned with ISO 14067 methodology, producing 1,000 units of an 8 oz cup with aqueous coating generates approximately 21.92 kg CO₂e, compared to 24.77 kg CO₂e for the equivalent PE-lined cup — a reduction of around 11.5%. Across a typical production run of 36,000 cups, the carbon saving is equivalent to the annual carbon sequestration of a mature 20-year-old tree.
Which coating should I choose for hot beverages versus cold beverages?
Aqueous coating performs well for both hot and cold beverages, offering leak resistance and heat tolerance suitable for coffee, tea, and cold drinks. PLA coating is also suitable for both, though it is particularly popular for cold cup applications. PE coating remains the most cost-effective option for standard hot cups where sustainability is not a primary requirement.
Can I get custom printing on eco-friendly coated cups?
Yes. All coating options — aqueous, PLA, and PE — are available with full custom flexographic printing. Minimum order quantities and sampling fees apply in the same way as standard cups. Contact us for artwork specifications and a sample quote.
