Plastic Sheeting provides the optimal economy pricing, performance, and toughness.Plasticsheetingcan be used for masonry, construction, landscaping and within a multitude of additionalindustries. Plasticsheeting is exceptionalfor covering and protecting skids, lumber, warehouse equipment, machinery, and construction materials. Plastic sheeting packaging provides optimal economy, performance, and toughness.
Below is a guide to the terminology generally used when deciding the best plastic sheeting option for your application.
Gloss:The films surface reflection of light. The degree of sheen of the surface.
Haze:The degree of cloudiness of the film. Indicates how clearly an object can be seen through the film.
Opaque:Film that inhibits light transmission. The opposite of transparent.
Tint:Tiny voids in the film, enabling water, air, etc. to pass through the film.
Translucent:A film that permits the transmission of light. Clear, transparent.
Film:Sheeting having a nominal thickness not greater than .010 inch (10 mil).
Tolerance:A specified allowance for deviations in weighing, measuring, etc
Mil:One thousandth of an inch
Density:Weight per volume
Ream:500 sheets, 2' x 3'. Equivalent is 3,000 sq. ft. or 432,000 sq. in
Basis Weight:The weight, in pounds, of 1 ream of film. Will vary on density and thickness.
Yield:The square inches of film yielded per pound. Will vary on density and thickness.
Orientation:Alignment of the crystalline structure in film in both the machine and transverse directions.
Shrink:The ability of film to conform to an object when reheated. A result of controlled orientation.
Impact Strength:The ability of a film to withstand shock loading, blunt puncturing, etc.
Tensile Yield:The pulling stress required to deform a given film specimen.
Tensile Break:The pulling stress required to break a given film specimen.
Elongation:A measure of how much a film can stretch over a given load profile.
Coefficient of Friction:The ratio of a frictional gravitational force to the perpendicular force of the two surfaces in contact.
Treat:A method of altering a polyolefin surface to render it receptive to inks, adhesives, etc.
Water Vapor Transmission Rate:Rate at which water vapor permeates a plastic film at a specified temperature and relative humidity.
Oxygen Transmission Rate:Rate at which oxygen permeates a plastic film at a specified temperature and relative humidity
Surface Resistivity:Measures the electrical resistance of the surface of the plastic.
Antiblock:A silica or DE compound added to film that roughens the surface to prevent blocking.
Antistat:A compound added to film that dissipates the accumulation of static electricity.
Slip:A fatty acid amide added to film to reduce surface friction.
UltravioletAbsorber:A compound designed to selectively absorb pass through UV rays.
UltraVioletInhibitor:A compound designed to selectively scavenge destructive free radicals set free by UV rays
UltravioletBlocker:A compound designed to selectively block pass through UV rays.
Vapor Corrosion Inhibitor:A compound added to film for the prevention of oxidation or corrosion of packaged parts.
Extrusion:The breaking down and reshaping of materials by forcing it through an orifice.
Low Density Polyethylene:An ethylene based thermoplastic polymer with a nominal density of .910-.925.
Medium Density Polyethylene:An ethylene based thermoplastic polymer with a nominal density of .926-.939.
High Density Polyethylene:An ethylene based thermoplastic polymer with a nominal density of .940-.965.
Linear Low Density Polyethylene:A low density, low pressure polymer resulting from the introduction of comonomers to control density.
Butene LLDPE:Lowest grade of LLDPE, this polymer still outperforms LDPE in strength and sealabilty.
Hexene LLDPE:Next level of LLDPE, this polymer has improved tear and impact over butene.
Super Hexene LLDPE:Highest level of LLDPE, has excellent tear strength and dart impact, with optics improving.
Octene LLDPE:Highest level of LLDPE, has excellent tear strength, very good dart impact and better optics.
Metallocene LLDPE:LLDPE with unsurpassed dart impact, very high clarity, good tear strength and very good hot tack.
Very Low Density Polyethylene:A low pressure copolymer with outstanding impact strength, stretch and low temperature sealabilty.
Ethylene Vinyl Acetate:LDPE that has been copolymerized with ethylene vinyl acetate to enhance strength and sealability.
Thermoplastic:Polymeric material capable of being repeatedly softened by heat and hardened by cooling.
Single Wound Sheeting:A single layer of film, cut on both sides.
Double Wound Sheeting:A double layer of film, cut evenly on both sides
Centerfold Sheeting:A double layer of film, cut evenly on one side, folded on the other.
J Sheeting:A double layer of film, cut to different lengths on one side, folded on the other.
M Sheeting:Centerfold sheeting thats folded inward on the crease side.
U Sheeting:A double layer of film, folded on both sides, with a (center) section cut out on one side.
Sheets on Roll:A continuous, single layer of film, separated by perforations and wound on a roll.
