Rather than using a cardboard frame backing that offers little protection or resistance against moisture, Poster Frame Depot offers three different variations of foamcore frame backings, as well as a corrugated plastic backing to ensure that your framed work has the best protection possible.
Our foamcore backing provides more protection for your photos, posters, and most artwork than a typical cardboard backing can. A lesser quality cardboard backing attracts mold and offers little protection from moisture seeping into your framed art work. Our high quality foamcore backing consists of a thick inner core of polystyrene, a stiff foam, with protective paper on either side. A corrugated plastic backing is resistant to moisture and most oils or solvents, making it ideal for protection against damp conditions and extreme handling.
When choosing a backing, it is important to consider two things: What is the value of your framed item, and where will you be hanging it?
Cardboard backings are unacceptable when framing anything of value. When framing a valued poster, picture or piece of artwork, it is important to select the correct foamcore backing.
If you are planning to hang your frame in a damp place like a basement, corrugated plastic is the best choice for protection from constant moisture and humidity. If your frame will be hanging somewhere more dry, any foamcore backing will offer plenty of protection.
Choices available are:
Standard White Foamcore
Our Standard White Foamcore is non-acidic. We suggest it be used for artwork that is expected to be framed for up to 50 years and is valued at less than $100.00. Available in sizes up to 42x62.
Acid Free Foamcore
Acid Free Foamcore is buffered with an Alkaline chemical which helps to combat the acids found in most posters or prints. Our suggested use is for artwork that is expected to be framed for upwards of 100 years and is valued at over $100.00. Available in sizes up to 32x42.
Black Foamcore is both black on the outside and has a black inner core. Black foamcore is typically used when framing matted records, shadow boxes or simply when the back of the frame must be black. Available in sizes up to 32x42.
Corrugated Plastic is a fluted plastic material used when extreme handling, moisture, constant humidity, or temperature changes are a concern. Our corrugated plastic backings have a smooth finish to them to ensure that your framed work remains flat and dry. Available in sizes up to 42x62.
Please note: Both a Lens Cover and Backing are required to properly use our type of frame.
