1. Expanded Polystyrene
Foam packaging and packing materials are available in recycled, antistatic, soft, rigid, thick, thin, sheets, rolls, blocks, cubes perforated, scored, tear apart and shapes for box inserts. Depending on the foam specified, colors include black, blue, pink, charcoal, gray, yellow, green, purple, white.
Q: What do I need to think about when packaging my product for shipment?
A: There is a basic starting point for any packaging project.
Q: How do I choose the best packaging materials for my product?
A: As a starting point, determine your major objectives.
Q: How do I measure a box?
A: Inside dimensions are always used when listing box measurements and given in the sequence of length, width and depth (height). A good “rule of thumb” is that the depth (height) is where the box opens, if you were to put a yard stick through the opening to opposite end; that is the depth. Of the remaining two dimensions, the length is the longest and the width is the shortest.
Q: What is EPS?
A: EPS is expanded polystyrene. It is a light-weight and rigid foam, which is produced from solid beads of polystyrene. An extremely cost effective packaging material, it is moisture resistant, a good thermal insulator, (insulation R-value of 4.0 per inch) and it is structurally strong (compression strength of 1000 lbs per square foot.) It is extremely versatile and may be fabricated into appropriate forms and customized shapes. Plastifoam's computer-guided cutting systems can duplicate any line pattern eliminating the need for expensive dies or molds.
Q: What is Polyurethane?
A: Polyurethane foam includes two types, flexible and rigid. The flexible foams that we use are open cell foams, used for packaging and available in a wide range of densities and colors. It has the ability to absorb shock from an impact and recover its original shape quickly. Its physical performance characteristics make it ideal for protecting fragile items. It can be cut or fabricated to many formats such as end-cap assemblies, top and bottom trays, convoluted (egg crate) or custom-fitted padding.
Q: What is Egg Crate Convoluted Packaging Foam?
A: It is flexible polyurethane foam which has interlocking peaks and valleys which gently cradle products, while firmly holding them in place. It is available in various densities and colors. The antistatic pink version is ideal for cushioning circuit boards and other static-sensitive items.
Q: What is Polyethylene?
A: Polyethylene is a plastic polymer extensively used as packaging foam. It is a tough, resilient, lightweight, closed-cell foam material commonly used for the cushioning of relatively high value and moderately fragile items. It is available in a wide range of densities and colors. It has high tensile and tear strength so that it withstands long periods of heavy use. Depending on its density it is generally very rigid, with less give in it than flexible polyurethane. It is a very strong and resilient cushioning material that is not damaged by initial impacts and recovers to maintain protection against repeated shocks. It can be cut into pads or blocks or custom die-cut to fit specific shapes.
Q: What is meant by Foam Density?
A: Density refers to the internal structure of a particular foam and is not a measurement of foam firmness. Firm foam is not always high density foam. Density is defined the weight in pounds of one cubic foot of material, or pounds per cubic foot (pcf.)
