Warp Bros

A Century of American-Made Plastic Innovation

Warp Bros. is one of America's most enduring names in plastic products, with a story that stretches back to 1924. Warp Bros. was founded when Harold Warp arrived in Chicago with his brothers and a patent for a pioneering plastic window material called Flex-O-Glass — originally conceived to help insulate his family's chicken coops. That spirit of practical, everyday innovation has defined the brand ever since.

From those humble beginnings, the company grew into a full-scale manufacturer of polyethylene plastic sheeting, consumer storage products, and protective covers for home, garden, and industrial use. Today, Warp Bros. operates manufacturing plants in Chicago and Dixon, Illinois, and remains a family-owned business now in its third generation of leadership — a rarity in modern manufacturing.

Quality You Can Measure

One of Warp Bros.' long-standing commitments is to what they call "full-weight, full-strength" plastics. Unlike lower-grade alternatives, Warp Bros. products are engineered to meet the actual thickness and weight specifications printed on the label. This attention to material integrity is a core part of why contractors, homeowners, DIYers, farmers, and gardeners have trusted the brand for decades.

All Warp Bros. products are manufactured in the United States, supporting American workers and ensuring consistent quality control from resin to finished product.

A Broad Range of Practical Products

The Warp Bros. catalog covers a wide spectrum of protective and storage solutions. Their heavy-duty plastic sheeting is available in multiple thicknesses and widths, suitable for everything from construction vapor barriers and concrete underlayment to painting tarps and outdoor covers. The iconic drop cloths are a go-to for painters and remodelers who need reliable surface protection that won't let moisture or paint seep through.

For storage needs, Warp Bros. offers a range of oversized plastic storage bags — including their popular Jumbo Banana Bag — designed to protect mattresses, artificial trees, seasonal furniture, and large equipment from dust, moisture, and insects. Their lawn and garden plastic products help gardeners and landscapers manage soil moisture, suppress weeds, and protect plantings through harsh weather.

Rounding out the lineup are ribbed shelf liners and floor runners, which protect surfaces from scratches, spills, and wear in garages, workshops, and pantries, along with heavy-duty trash can liners built to handle tough clean-up jobs without splitting at the seams.

Why Warp Bros. Stands Out

• Nearly a century of continuous family ownership and American manufacturing
• Full-weight plastic guarantee — what the label says is what you get
• Broad product range covering home, garage, garden, and industrial applications
• Consistent quality built on generations of plastics expertise
• Products engineered for real-world durability, not just shelf appeal

Whether you're prepping a job site, protecting a prized piece of furniture, or getting your garden ready for winter, Warp Bros. brings proven American craftsmanship to every roll, bag, and liner they produce.
