It´s important that you cushion the contents of your package properly.
Please be sure that you wrap each item separately. Fragile articles need both suitable separation from each other and clearance from the corners and sides of the box.
Each item should be surrounded by at least two inches (five cm) of cushioning and be placed at least two inches (five cm) away from the walls of the box. This will protect your items from product-against-product damage and shield them from the shock and vibration that can be conducted from the exterior of the box to its contents in transit.
Please use proper cushioning material, combined with a strong outer container, to protect your shipment fully. Make sure you use enough cushioning material to ensure that the contents do not move when you shake the container.
Improper cushioning material includes clothing, blankets, and pillows. Instead, please use the materials listed below to cushion and protect your shipment:
Air-encapsulated plastic (bubble pack)
Designed to protect and cushion lightweight items Used in multiple wraps and layers to ensure that the item is completely protected, especially on corners and edges
Inflatable packaging (air bags)
Used primarily as void-fill materials for lightweight items Not recommended for items with sharp corners or edges Extreme hot or cold temperatures may affect the ability of air bags to provide adequate product protection.
Expanded polystyrene "peanuts"
Used primarily as void-fill material for lightweight items Overfill the box with peanuts, gently close the flaps, and seal securely Do not use with flat or narrow products that may move to the edge or bottom of the carton in transit Due to the shifting and settling properties of peanuts, it is recommended that a minimum of three inches of cushioning be used around the contents
Engineered foam enclosures
Materials may include expanded polystyrene, polyethylene, polypropylene, or copolymers Enclosures should be pre-engineered for specific products
Foam-in-place
(a foam, sprayed into the box or mixed in packets, that expands and forms a protective mold around contents) Must be properly used, with even foam distribution around the contents Select appropriate density of foam to meet packaging needs, which can range from void-fill applications to high-performance cushioning
Corrugated liners and inserts
May be added to the package to increase strength and improve package performance
Crumpled kraft paper
Used primarily as a void-fill material for light-to-medium weight, non-fragile items and items that are suitable for such packing materials
Must be tightly crumpled
Place at least four in. (10 cm.) of paper between contents and outer box
