Films Protective Company is a manufacturer of string reinforced polyethylene film for industrial covering, temporary construction protection and waterproof auxiliary covering. PE layers are laminated around an embedded string or scrim grid to slow tear propagation, improve puncture resistance and maintain dimensional stability during unfolding and fastening. Clear, white and blue grades can be selected by covered area, fixing method and expected outdoor period. Thickness, basis weight, roll width and edge construction are reviewed before sample approval.
Product Overview
This reinforced polyethylene plastic film is made for work areas where ordinary PE sheeting may split after snagging, puncture or edge damage. The grid sits inside the laminate rather than on the surface. Square, diamond and diagonal scrim structures are available, while machine-direction strings can improve control when wide rolls are lifted and unfolded.
String reinforced polyethylene film uses a different principle from high density cross laminated polyethylene film. Cross-laminated material distributes stress through oriented layers. This product uses an internal cord grid to localize damage. Grade selection should consider scrim density, thickness, basis weight, roll width, seam quantity and site fixing method. Wider rolls reduce seams, but they must still suit handling and perimeter fastening.
Benefits
- Embedded scrim helps stop a cut or puncture from spreading across the sheet.
- Internal reinforcement supports stable unfolding, folding and temporary fastening.
- Wide rolls reduce seams across enclosures, equipment covers and protected floors.
- Reinforced bands and pre-punched eyelets support fixing points under repeated stress.
- Clear, white and blue grades support visibility, heat management or site identification.
- UV-stabilized and FR / NFR options can match project duration and required test documentation.
How Does the Embedded String Grid Limit Tear Propagation?
Once a cut reaches the internal grid, the surrounding scrim interrupts the tear path. Performance still depends on the selected pattern, grid density and edge condition. For vertical enclosure work, samples should be checked after cutting, folding and fastening simulation. Corners, cut edges, reinforced bands and eyelet holes need attention because uneven tension often concentrates around the perimeter. The laminate should also be checked for edge delamination after repeated handling.

What Should Be Checked Before String Reinforced Polyethylene Film Is Used Outdoors?
Polyethylene film UV resistance should be confirmed for the selected grade rather than estimated from thickness alone. Review sunlight intensity, climate, color, scrim density, installation tension and the planned removal schedule. When used as a polyethylene sheet for waterproofing support during short-term work, the material should not be treated as a permanent waterproof membrane. Before volume production, verify roll width, core specification, folding or winding format, edge condition and fixing method with an actual-use sample. Retain the approved sample and lot identification so repeat orders match the agreed structure.
FAQ
Is string reinforced polyethylene film stronger than ordinary PE sheeting?
Its embedded grid helps control tear propagation and improve puncture resistance. Final performance depends on thickness, basis weight, scrim pattern and fastening conditions.
Can the roll width and reinforcement pattern be customized?
Yes. Roll width, length, scrim pattern, edge structure and folding format can be matched to the covered area and installation method.
Is the film suitable for outdoor construction protection?
Yes. UV-stabilized grades are available for defined outdoor periods. Select the grade based on project duration and climate.
Are reinforced bands and eyelet holes available?
Yes. They support more secure perimeter fastening in enclosure projects.
