Why do packaging boxes have an odor? The smell primarily comes from inks, adhesives, laminations, and the materials themselves. It is common for newly manufactured boxes to have a slight scent; the odor is particularly noticeable in boxes that have just come off the production line, as the adhesive has not yet fully cured. Most odors will dissipate after the boxes are left in a ventilated area for a period of time.
What other safety considerations are there? Heavy metals in inks, fluorescent whitening agents, and plasticizers are key inspection points. Packaging destined for Europe, the US, or Japan faces stricter material safety requirements, so relevant test reports must be prepared. Safety is paramount; keep material lists and reports on file.
Is an odor considered a quality issue? A strong, pungent, and persistent odor is a quality issue that warrants a resolution; a mild “new box smell” is normal and will fade with time. To determine what constitutes a problem, agree on standards when placing the order so there is a basis for acceptance.
How can odor issues be avoided? Take three steps: choose eco-friendly inks and adhesives, ensure thorough drying after production, and ventilate the boxes to let the smell dissipate before shipment. Build time into the delivery schedule for airing out the boxes; do not pack and ship them immediately after production. Clearly communicate odor requirements to the manufacturer so they can schedule the necessary time.
How long does the odor last? It depends on the materials and processes used. Boxes made with water-based inks, eco-friendly adhesives, and solvent-free processes have milder odors that dissipate quickly, whereas oil-based inks and solvent-based adhesives produce stronger odors that linger longer. Choosing eco-friendly materials and processes is the fundamental solution.
What are the requirements for food and cosmetic packaging? Requirements are strict for packaging that comes into direct contact with the product: low odor, food-grade materials, and compliance with contact regulations in the target market. For cosmetic gift boxes, one must also consider whether the product might absorb the packaging’s odor. It is safer to choose a manufacturer with experience in food packaging for these types of orders.
Can the odor be detected during prototyping? Sample quantities are small, so the odor is often fainter than in mass production; a scent-free sample does not guarantee the bulk order will be scent-free. The odor should be specifically checked after the first batch of mass production, with third-party testing conducted if necessary. Samples are for evaluating the style, while odor should be verified on the actual mass-produced goods.
