A Batch of Samples That Didn't Add UpAbout a month ago, a pet snack manufacturer sent us two rolls of film from another supplier. They wanted us to "take a look."

An electronics exporter friend of mine asked me to look at a quotation last month. He needed a batch of custom-structure PET/AL/PE composite film for moisture-proof packaging — about 800 kilograms. The supplier's MOQ was 1,500 kg with pricing based on that volume. He asked if they could just produce

Delamination in Aluminum-Plastic Composite Films: Analysis of Adhesive Selection and Insufficient CuringA pet food exporter got a panic call last month.
