Costco has updated its testing rules for packaging materials. The new focus: non-toxic, low-chemical packaging.
Costco 更新了包装材料测试规则，新重点：无毒、低化学物质的包装。
What is changing ／ 有哪些变化
- Total fluorine limit: 100 → 50 mg/kg by 2027. Twice as strict.
总氟上限：2027 年起从 100 降到 50 mg/kg，严格一倍。 - 10+ chemical groups are screened, such as phthalates, bisphenols and formaldehyde.
筛查十多类化学物质，例如邻苯、双酚、甲醛。 - Every part of the package is in scope: paper, board, every ink color, glue, tape and labels.
包装的每个部件都要检测：纸、纸板、每种颜色的油墨、胶水、胶带、标签。 - Suppliers must declare no added PFAS. No declaration means no pass.
供应商须声明未添加 PFAS；没有声明，就无法通过。
Why it is hard ／ 为什么不容易
Fluorine and phthalates are the two most common failure points for packaging factories. Both can enter from many places in the supply chain, so they cannot be fixed at the last step. They must be controlled from the raw materials.
含氟与邻苯是包装工厂最常见的两个超标项目。它们可能来自供应链上的许多环节，无法在最后一步补救，必须从原材料开始管控。
How ZEO handles it ／ ZEO 怎么做
- Controlled paper sources. We work with paper suppliers that can meet the new limits.
指定纸材来源：选用能达到新限值的纸材供应商。 - Proprietary process know-how. Our special process keeps fluorine and phthalates under control.
特殊工艺：以我们掌握的工艺，稳定管控含氟与邻苯。 - Testing planned from day one. Materials are chosen with the test plan in mind, not after.
从设计第一天规划检测：先定检测计划，再选材料。 - Verified carbon data. Our PDQ carbon footprint is calculated to ISO 14067 and third-party verified.
经查证的碳数据：PDQ 碳足迹依 ISO 14067 计算，并经第三方查证。
What it means for buyers ／ 对客户的意义
Not every packaging supplier can meet the new rules every time. Choose a partner that controls materials, not just printing. Talk to us early in your program.
并不是每家包装供应商都能稳定达到新标准。请选择能管控材料、而不只是负责印刷的伙伴，并在项目初期就与我们沟通。
This is a high-level summary. Final requirements follow Costco’s current protocols for each program.
以上为概要说明，实际要求以 Costco 各项目的最新协议为准。
