Puropak Attached Cap Passes SGS EN 17665 Test | EU PPWR Compliant Spout Pouches

For brands exporting flexible packaging to the European market, compliance with the EU Single-Use Plastics (SUP) Directive and PPWR regulations has become a non-negotiable market access requirement. Many pouch manufacturers struggle to deliver reliable attached cap solutions that meet official EU performance standards. At Puropak (Foshan) Co., Ltd., we are pleased to announce that our patented attached spout cap has successfully passed the SGS EN 17665:2022 + A1:2023 conformity test as of August 25, 2026.

Regulatory Background: Why EN 17665 Is The Compliance Benchmark

EN 17665 is the harmonized European testing standard for attached caps on beverage containers, serving as the core technical reference for compliance with the EU SUP Directive. Full regulatory context on tethered cap requirements and enforcement timelines is available from Food Health Legal SUP Directive packaging guidance. The standard evaluates two core performance dimensions critical for market access: attachment strength and long-term attachment reliability.

Products validated to this standard are legally presumed to meet SUP Directive tethered cap requirements, which is essential for clearing EU customs and passing retail supplier audits. For a detailed technical breakdown of the standard’s test clauses and acceptance criteria, reference ANSI EN 17665:2022+A1:2023 standard preview.

Test Results: Both Core Assessments Earn Full Pass Rating

The SGS audit evaluated our patented attached cap design against both mandatory clauses of the EN 17665 standard, with passing results across all performance metrics.

Under Clause 4.2, the attachment strength test verifies that the cap remains firmly connected to the flexible pouch under applied pulling force. For pouches without an integrated neck finish, the minimum required tensile resistance is 12 newtons. Our attached cap design achieved a full PASS result, confirming it will not detach or break off during normal consumer use and transit handling.

Clause 4.3 covers reliability through repeated open-close cycle testing. The requirement specifies a minimum of 15 complete open-close cycles for resealable caps. Our patented attached cap also earned a PASS rating, proving stable, consistent performance through repeated opening and closing. The cap remains permanently connected to the pouch body instead of separating and becoming loose plastic waste, aligning with EcoTensil EU SUPD implementation guidelines for plastic litter reduction.

Market Value for EU-Exporting Brands

Many European buyers and distributors now actively source pouch suppliers with valid third-party EN 17665 test reports as a pre-qualification requirement. Without a qualified attached cap solution, beverage, liquid food and household product pouches cannot meet mandatory EU market access rules. SGS official EU single-use plastics certification services notes that uncertified attached cap designs are the single top cause of EU customs holds for flexible liquid packaging shipments.
