A Phone Call That Changed Everything: Chemical Bags Being Eaten Through in TransitLast month, a client who manufactures industrial cleaning powders sent me a set of photos.

A Bag of Bone-In Steak Gone WrongLast month, a client who vacuum-packs frozen bone-in steaks called me, sounding utterly frustrated. "Our packaging passes every factory QC check — 100% pass rate on outgoing inspections," he said. "But by the time it reaches consumers, there are holes in the bags. Th

A Bag of Longjing That Lost Its SoulA client of ours who makes small tea sachets told me a story I haven't forgotten. He exports primarily to Japanese and European tea brands. Last year, he shipped a batch of pre-Qingming Longjing green tea to Japan, packed in standard kraft paper metallized bags. W

A Batch of Pet Food Bags Thrown AwayLast month, a North American pet food client emailed us in a panic. He'd just received a batch of composite film packaging bags, and during printing, the ink peeled off in large sheets. After lamination, the peel strength was under 1.5 N/15mm — well below the indu
