What does a buyer check before switching packaging suppliers?
Answer
They check that your material is compliant for their contents, that the pack survives their distribution route, and that artwork changeover will not stall a production run. Migration data, transit test results and a stated artwork approval process cover the three risks that actually block a switch.
A packaging manager is evaluating whether changing supplier is worth the requalification work.

Related questions
What is the single most useful page for a packaging supplier?
A format and capability table: pack types, size ranges, materials, print processes, colour counts and minimum order quantities. It answers the first four emails of every enquiry and lets buyers rule themselves in or out without a call.
How should sustainability claims be handled?
State the material, the recycled content as a percentage of what, and the certification body where one exists. Unqualified claims like "eco-friendly" are actively counterproductive with professional buyers, who now expect a substantiated basis for any environmental statement.
Should minimum order quantities be public?
Yes. MOQ is the most common reason a packaging enquiry fails, and discovering it on the third email wastes both sides. Publishing it costs you enquiries that would have failed and wins you credibility with the ones that would not.
