Introduction to Tethered Caps for Spouted Bags
Tethered caps for spouted bags are a new way to package items. The cap stays attached to the spouted pouch, even when it’s open. This is different from regular caps that come off when you unscrew them.
This idea came up because of worries about plastic pollution. People were throwing away loose caps, which ended up in oceans and nature. First seen in bottles, now spouted pouches use them too.
When you open a spouted bag with a tethered cap, the cap stays on the spout. It’s held by a thin plastic strip or hinge. This lets you pour the product without losing the cap. It also keeps the cap with the package, helping to keep things fresh and preventing spills.
2. The Environmental Impact & Regulatory Landscape
EU Single-Use Plastics Directive Requirements
The EU’s Single-Use Plastics Directive started in July 2021. It’s making tethered caps a global standard. By July 3, 2024, all plastic drink containers must have caps that stay attached during use.
This rule affects all plastic packaging with caps, including spouted pouches. It’s for containers up to 3 liters, including composite packaging.
Other Global Regulations
Other places are following the EU’s lead:
– **United Kingdom**: The UK has also adopted the EU’s tethered cap rules, even after leaving the EU.
– **Canada**: They’re thinking about making caps stay attached too.
– **California (USA)**: A bill there might require caps to stay on bottles.
– **Australia**: They’re working on a plan that could include tethered caps.
### Compliance Timelines
Businesses need to act fast if they sell in Europe:
– **July 3, 2024**: All products must meet the EU’s new rules.
– **UK market**: The UK will follow the EU’s timeline.
– **North American markets**: They’re still figuring things out, but it might be 2025-2027.
– **Asian markets**: They’re starting to use tethered caps voluntarily, but rules might come later.
Companies selling worldwide should make packaging that meets the EU’s standards. This way, they can comply everywhere.
