Top packaging questions
Short answers for common packaging learning topics.
What does GSM mean in paper packaging?
GSM means grams per square meter. It helps describe sheet weight, but stiffness and strength also depend on fiber, coating, and structure.
Is kraft paper always recyclable?
Clean, uncoated kraft paper is often easier to recycle, but heavy coating, lamination, food residue, or mixed construction can change recovery options.
What makes food packaging suitable for food use?
The material, coating, ink, adhesive, temperature, and direct or indirect food-contact condition all need to match the intended use.
How are folding cartons and corrugated cartons different?
Folding cartons use paperboard for lighter retail presentation, while corrugated cartons use fluted board for stronger shipping and stacking contexts.
Is biodegradable the same as compostable?
No. Compostable claims usually depend on defined standards and processing conditions, while biodegradable is broader and needs more context.
