Packing material vocabulary

Question

In English, there are quite a few words to describe materials used to pad and insulate packages that are being shipped from one place to another:

• packing peanuts or foam peanuts are individual pieces of small foam
• bubble wrap describes sheets of plastic with many small embedded bubbles of air
• Styrofoam is a material often found padding objects during shipment
• shrink wrap is a plastic film that forms a seal over an object
• padding refers generally to any material that cushions objects
• packing materials is a general term describing any of the objects above

How would each of these terms be best translated to Spanish?

Answer 1

Spain:

• packing peanuts: there's no formal word. On my neck of the woods, we use "palomitas" (popcorn)
• bubble wrap: papel de burbujas
• Styrofoam: again, no formal word that I know of. I use "porexpán", which I believe is a commercial name for the product (you can check other names elsewhere in http://es.wikipedia.org/wiki/Poliestireno_expandido )
• shrink wrap: no specific name... "plástico"
• padding: relleno
• packing materials: material de embalaje or material para empaquetar

Answer 2

In Bolivia, I learned "PLASTOFOR" for STYROFOAM, and in Chile we call it "PLUMAVIT". All three are presumably brand names or trademarks for "poliestireno expandido", the generic name for a relatively modern material. Shrink wrap is known in Chile as "alusa" or as "estretch film".
