Finished Product Protection Standards for Distribution Boxes
The Safe Quality Food Institute's (SQFI) SQF Codes, edition 8 were updated and redesigned in 2017 for use by all sectors of the food industry from primary production to storage and distribution and included a food safety code for retailers. They replaced the SQF Code, edition 7. Packaging serves a purpose far beyond aesthetics—it ensures that products remain intact and undamaged, whether they are being shipped across vast distances or stored for prolonged periods. To achieve this, businesses must adhere to globally recognized standards like ASTM D642, ASTM D4169, ISO. Understanding and implementing ASTM packaging standards is crucial for your product's journey from conception to consumer. What is ASTM? ASTM stands for the American Society for Testing and Materials, which is known today as ASTM International. 50 -- Minimum requirements for the storage and handling of prescription drugs and for the establishment and maintenance of prescription drug distribution records.
