Shipping Packaging Materials Solution Reference Standard: Relevant material and performance testing standards include ASTM D1693 for polyethylene environmental stress-cracking resistance, plus material-specific inspection logic for leak testing, dimensional control, and packaging protection. Short Answer Packaging materials for shipping are not only cartons, fillers, and tape. For plastic bottle packaging, the inner PE, PET, or PP container often becomes the first load-bearing, sealing, and abrasion-control component during transit, so shipping reliability depends on bottle material behavior, neck precision, wall-thickness control, and packing separation. Shipping damage is often blamed on the outer box, yet many failures start inside the box. A bottle wall that is too thin at a corner, a pump … 続きを読む

Exclusive Alcohol Spray Bottles: Sealing Logic for Low-Viscosity Liquids Reference Standard: Relevant material and performance testing standards, including ASTM D1693 for environmental stress-cracking resistance in polyethylene materials and practical leak-performance validation for pump-and-sprayer packaging. Short Answer Alcohol spray bottles should be specified as low-viscosity liquid packaging, not simply as ordinary cosmetic spray bottles. The key risk is not only the bottle material, but the combined behavior of PET, PE, PP, the sprayer, the neck finish, and the sealing interface under filling, packing, and transit conditions. When Low-Viscosity Liquid Changes the Definition of a “Small Spray Bottle” An alcohol spray bottle looks similar to a travel spray bottle, a cosmetic spray … 続きを読む
