The semi-automatic PET blow molding machine’s principal commercial advantage over an automatic machine is not throughput — it is format flexibility. A contract bottler running 20 different SKUs in monthly batches of 3,000–15,000 bottles each would require an... von Folge | Aug. 19, 2026 | ISBM Machine Blog
Semi-automatic PET stretch blow molding machines occupy a specific and well-defined position in the packaging equipment market: they are the correct tool for production volumes, container geometries, and operating environments where a fully automatic machine is... von Folge | Aug. 19, 2026 | ISBM Machine Blog
A PP baby bottle that fails in the sterilizer is a product recall risk, a consumer complaint, and a material science problem that originates at the blow molding machine. The bottle’s ability to survive steam sterilization at 121°C, microwave sterilizer cycles at... von Folge | Aug. 19, 2026 | ISBM Machine Blog
PP baby bottle production runs at higher defect rates than equivalent PET bottle production for reasons that are intrinsic to the material — the absence of strain hardening, the narrower blow temperature window, and the need for precise crystallization control during... von Folge | Aug. 19, 2026 | ISBM Machine Blog
Baby bottle material selection is a decision made at the intersection of food safety regulation, thermal resistance engineering, and consumer market expectation. PET dominated the baby bottle market until bisphenol A (BPA) safety concerns, which were directed at... von Folge | Aug. 19, 2026 | ISBM Machine Blog
Pharmaceutical container design decisions are validated, not just engineered — and the intended number of fill cycles is one of the variables that feeds the validation. A container designed and validated for single use that is refilled in practice represents an...
