Clear Poly Tubing 4 mil 30″ x 4 mil 750’/roll

Insulation Batt & Round Stock Poly Tubing — 30″ 4 mil LDPE | 750ft Roll

4 mil LDPE clear poly tubing wound on a 3″ core in a 750-foot roll, 30″ lay flat width (approximately 19″ expanded diameter). Manufactured from 100% virgin LDPE resin with even wall thickness for consistent cut-to-length sleeving of insulation batts, large diameter cylindrical stock, lumber bundles, and round goods. FDA/USDA compliant for incidental food contact.

Specs: 30″ Lay Flat (approx. 19″ expanded dia.) | 4 mil | LDPE | 750ft/Roll | 3″ Core | FDA/USDA Compliant

Applications

• Insulation batt and roll goods sleeving for moisture protection
• Large diameter round stock and bar stock bundling
• Lumber and dimensional board bundle wrapping
• Cylindrical product and core sleeving
• Industrial roll and coil end-cap protection

Features

• 30″ lay flat expands to approximately 19″ diameter for large cylindrical contents
• 4 mil heavy gauge — resistant to puncture and abrasion during material handling
• Wound on 3″ core with 1″ diameter core plug for roll dispensing fixtures
• Cut-to-length format — size bags to exact content length without waste
• FDA/USDA compliant 100% virgin LDPE resin

Material Notes

Made from 100% virgin Low Density Polyethylene (LDPE) resin manufactured to exact wall thickness specifications for consistent sealing performance. 4 mil gauge provides the puncture resistance needed for large cylindrical items where surface contact pressure can stress thinner gauges. Core dimensions (3″ core, 1″ plug) are standard for powered unwind roll dispensers. FDA/USDA compliant for incidental food contact.

Use Case Notes

30″ lay flat is equivalent to approximately 60″ of circumference — suitable for cylinders up to ~19″ in diameter when fully expanded. This makes it appropriate for insulation batt rolls (typically 15″-23″ wide), large bar stock and tube bundle sleeving, and cylindrical product end protection. At 750 feet per roll, this provides significant run length for production sleeving or warehouse-level protection applications. Heat seal, tie, or tape both ends to create a complete moisture and dust barrier.

Common Questions

Q: What is the actual expanded diameter of 30″ lay flat tubing?
A: 30″ lay flat = 60″ of circumference. Dividing by π (3.14) gives approximately 19″ in diameter when fully expanded. Allow clearance for the contents to slide in without forcing the film.

Q: Can this tubing be heat sealed after filling?
A: Yes. Standard impulse or bar heat sealers work with 4 mil LDPE tubing. Heat sealing both ends creates a secure moisture and dust barrier. The tubing can also be tied, taped, or stapled shut.

Q: Is this tubing suitable for outdoor storage?
A: LDPE poly film provides moisture and dust protection but is not UV-stabilized. For long-term outdoor storage under direct sunlight, consider UV-resistant black poly film instead.

Why Buy

750 feet per roll, 30″ lay flat on a 3″ dispensing core, and 4 mil heavy-gauge LDPE construction make this a practical production sleeving solution for insulation manufacturers, building material distributors, and industrial operations requiring moisture-resistant cylindrical packaging for large round stock or bundled materials. FDA/USDA compliant resin adds flexibility for food-adjacent applications.
