LPL - Low Pressure Laminate
LPL or Low pressure laminate (Also known as Melamine) is thermally bonded to particleboard or MDF panels. LPL must be applied to the front and back of the panel to keep the panel balanced. Sometimes a brown backer is applied to the bottom if color is not needed. This is produced in higher volumes than High Pressure Laminate (HPL). It is thinner (about .007") than HPL and is more economical. Since it is thinner, it has less impact resistance than HPL. The insides of cabinets, store fixtures, POP displays, and shelving are common uses of this product.
HPL - High Pressure Laminate
HPL or High Pressure Laminate is about the most durable laminate available. It is made of several sheets of paper that get bonded together using high pressure presses. It is used in many horizontal applications such as counter tops and higher quality table tops. On vertical surfaces, it is commonly used for doors and drawer fronts of cabinets. HPL has higher impact resistance than most other laminates. The product gets glued on to the panel generally using a PVA glue. Usually a backer is used to prevent warping or the colored laminate is on both surfaces.
RTF - Rigid Thermo Foil
RTF is a tough, rigid and decorative film that is applied to a substrate, usually MDF, with heat, pressure and adhesive, and which creates a very attractive and durable surface. The RTF process is suitalbe for most worksurfaces, and RTF is available in a wide range of colors, as well as wood grains, metallics, faux stones and even MDF. It also is practical to specify custom RTF colors or patterns for large orders.
Since RTF accurately and uniformly conforms to the shape of its substrate material, your design can include curves, bevels, coves, bumps, embossing, debossing and reveals, both along edges and around corners. The finished surface is attractive, smooth and seamless.
