EU Exempts Aluminum Caps from Tethering! Ignore Artwork Declarations and PPWR Will Still Hold You Up

The EU determined that the recycling benefits and technical limits of aluminum caps justify an exemption under the SUPD (Single-Use Plastics Directive, regulations aimed at curbing the environmental impact of specific plastic products)

Talking recently with wine, spirits, and skincare clients selling into Europe, everyone was stressing over the 2026 PPWR (Packaging and Packaging Waste Regulation) tethering mandate

Caps were supposed to stay attached to beverage containers. That is easy enough for plastic bottles, but forcing metal cap manufacturers to retool their molds was an impossible financial hit

According to recent reporting from Packaging Insights, the EU finally gave a clear answer: aluminum caps will not require mandatory tethering

This means export brands save huge budgets on structural redesigns, and capping machines on production lines will not need a total overhaul

The top priority is updating the plastic content declaration on your packaging artwork so it matches your latest material certifications down to the letter

Do not assume you can blindly reuse old artwork files just because the structure stays unchanged

In practice, nearly all aluminum caps use a thin plastic liner inside to prevent leaks

Now that tethering is off the table, EU customs inspectors will zero in directly on your material composition declarations

If prepress staff send old artwork straight to press without accurately reflecting that plastic liner in the material callouts, the shipment will not match the paperwork when it lands at European ports, and you will face a full shipment rejection

Brands spent years chasing FSC (Forest Stewardship Council, an international certification promoting sustainable forestry) logos, yet they routinely trip up on multi-material details like this

Stick strictly to Mai Strategy's Three Prepress Gates, aligning SKU specifications with material certifications before sending files to print

To avoid this kind of fatal, rookie mistake, designers and print buyers need to bring compliance checks straight to the front lines

Walk through these three steps before handing off files:

・1. Request updated material specs: Proactively ask your client for the exact composition sheet from the aluminum cap supplier to verify the plastic liner ratio

・2. Verify artwork markings: Cross-check recycling symbols and material warnings on old files against physical documentation to confirm they match

・3. Confirm finishing registration: Skipping tethering means eyemarks stay the same, but still verify that margins on the updated label artwork meet die-cutting tolerances

If you manage dozens of export SKUs and worry about missing something, teaming up with a printer that knows the regulations is your safest bet

When MINDS handles high-end custom commercial print runs, prepress screens client artwork for regulatory landmines beforehand to keep risks as low as possible

・The EU officially exempts aluminum caps from SUPD tethering rules, saving export brands steep structural tooling costs

・Material declarations on artwork are the new audit priority, meaning old packaging files must never be reused blindly

・Leakproof plastic liners inside aluminum caps must be declared accurately on labels to prevent cargo rejections at European ports

This exemption looks like relief on the surface, but it really shifts compliance pressure from mechanical engineers onto prepress production staff

Print shops can no longer act as passive jobbers that just receive files, they must know how to read and interpret regulatory standards at the prepress stage

Adopting SaaS tools that compare artwork versions and check compliance wording will be an essential investment for small and mid-sized printers looking to cut customs detention risks
