Humidity, polluting gases and dust are the main factors capable of damaging art objects. This industrial product is a composite material based on aluminium foil made into a complex lamination of polyester and polyethylene. It can be heat-sealed with a CXD Criss Cross welder to ensure highly efficient moisture protection of box interiors for artwork or museum objects during shipping. It is also useful for making envelopes and dust covers and as a moisturebarrier in picture frames. It is commonly specified for covering and encapsulating wooden surfaces in showcases in order to act as a barrier against acetic acid and other corrosive gases emanating from the wood. It can be made into pouches suitable for vacuum-packing or anoxic storage and pest-eradication treatments.
