Construction Film Market

6.60 billion square metres of Chinese floor space stood under construction in 2025, the counted stock that the National Bureau of Statistics of China reported on 20 January 2026, down 10.0% on 2024, with newly started space down 20.4% to 587.70 million square metres. The construction film market covers polyethylene, PVC, polypropylene and PET sheet used on building and civil sites as vapor retarders, damp proof and gas membranes, roof and wall underlays and temporary protection. Douglas Insights sizes it at USD 17.37 billion in 2025, from 7.12 million tonnes at an average ex-works USD 2.44 per kilogram, and at USD 27.77 billion by 2035, a 4.80% revenue CAGR. Ownership shifted on 30 April 2025, when Amcor completed its all-stock combination with Berry Global, bringing one of the largest film converters under a single packaging group. The study belongs to our construction materials coverage, and the inputs are listed in our research methodology.

Which resin leads construction film sales: LDPE and LLDPE, HDPE, PVC or PP?

LDPE and LLDPE lead with 44.7% of 2025 construction film revenue, or USD 7.77 billion, because blown polyethylene sheet is the cheapest way to cover a slab, a crawl space or a stud wall. PP grows fastest, at 5.54% a year, as spunbond and woven underlays replace felt on roofs.

LDPE and LLDPE construction film rises to USD 12.72 billion by 2035, carried by vapor retarders and protective sheeting that builders buy by the roll. HDPE film, at USD 3.01 billion and a 17.3% share, wins where puncture resistance matters: under-slab sheet over crushed stone and reinforced tarpaulins. PVC holds 13.6%, or USD 2.36 billion, through damp proof courses and pond and tanking membranes; its 3.62% growth is the slowest, as polyolefin grades take share. PP is worth USD 2.07 billion and climbs to USD 3.54 billion, since breathable roof and wall underlays are now the default in new European and North American housing. PET and other resins carry USD 2.17 billion, a 12.5% share, through metallised reflective layers and laminated gas membranes.

How is construction film revenue split across vapor retarders, underlays and protective sheeting?

Vapor retarders and under-slab sheet take 31.4% of construction film value, or USD 5.46 billion in 2025, by Douglas Insights estimates. Protective and temporary sheeting follows at 26.8%, because every concrete pour, paint job and abatement site consumes thin poly that is discarded within weeks.

Roofing and wall underlays are a USD 3.28 billion construction film application, and the closest neighbour to the housewrap products covered in our Building Wrap Market report. Damp proof membranes carry USD 2.29 billion, 13.2% of value, laid under ground-floor slabs in the UK, Ireland and much of northern Europe. Gas and radon membranes are the smallest group, at USD 1.69 billion or 9.7%, but they sell at multiples of plain sheet prices because they are laminated with aluminium or multilayer barrier resins. Film made for packaging rather than sites, such as machine-direction oriented sheet, sits in our MDO PE Films Market study.

Why are housing completions and slab pours lifting construction film demand?

Four sources add 3.10 points a year of construction film volume growth: housing completions 1.12 points, industrial and infrastructure sites 0.86, heavier under-slab specifications 0.71 and Gulf and South Asian urban building 0.41. Together they take tonnage from 7.12 million in 2025 to 9.66 million in 2035.

Housing completions: 1.12 points

Residential work is the largest construction film buyer, at USD 8.27 billion or 47.6% of 2025 value in our model. The US Census Bureau counted 1,358,700 housing starts in 2025, against 1,367,100 in 2024, and 1,497,800 completions; 943,000 of the starts were single-family homes, each with a slab or crawl space that needs a vapor retarder. Completions running above starts means the 2025 pipeline is still being closed in, wrapped and sheeted. Housing contributes 36.1% of the volume leg, the largest single piece.

Industrial and infrastructure sites: 0.86 points

Warehouses, data halls, tunnels and bridge decks use construction film as curing covers, slip sheets and temporary enclosures. Industrial and infrastructure work is a USD 3.91 billion end use, 22.5% of 2025 value. Douglas Insights expects it to add 0.86 points a year, as large slab-on-grade buildings need tens of thousands of square metres of 10-mil to 15-mil sheet each. A single 1,400 square foot roll of 15-mil sheet weighs about 45.6 kilograms, so every large slab moves real tonnage.

Heavier specifications and Gulf building: 0.71 and 0.41 points

Designers are moving under-slab construction film from 6-mil polyethylene to 10-mil and 15-mil Class A sheet, which more than doubles kilograms per square metre. We count that thickness shift as 0.71 points of tonnage growth with no extra floor area. Urban building in the Middle East and South Asia adds 0.41 points; the Middle East and Africa grows 5.11% a year in our model. Commercial sites, worth USD 5.19 billion, take the remaining 29.9% of value and sit across all four drivers.

Put together, the four drivers explain why construction film tonnage keeps rising even while Chinese starts fall. Housing supplies 36.1% of the 3.10-point leg, industrial and infrastructure 27.7%, heavier gauge 22.9% and Gulf and South Asian building 13.2%. The gauge effect is the least visible: a contractor who moves a 2,000 square foot slab from 6-mil to 15-mil sheet buys about 39.1 more kilograms of construction film for the same floor. Repeated across 943,000 single-family starts, that shift alone would add about 36,900 tonnes a year in the US. Gauge is the quiet driver.

Which headwinds cut construction film tonnage, from Chinese housing starts to resin swings?

Three drags remove 1.13 points a year from a gross construction film volume rate of 4.23%: the Chinese property slump 0.58 points, polyethylene resin swings 0.34 and reuse and reduction programmes 0.21. The 3.10% net leg already reflects all three.

China is the heaviest drag. The National Bureau of Statistics put 2025 real estate development investment at 8,278.8 billion yuan, down 17.2%, and completed floor space at 603.48 million square metres, down 18.1%. Fewer starts mean fewer slabs, fewer damp proof layers and less site sheeting, so we remove 0.58 points of construction film growth until starts stabilise.

Resin is the second. Contractors watch it closely. Polyethylene is most of the cost of a roll of construction film, so price spikes push contractors to thinner gauges or to reuse covers. Douglas Insights puts that drag at 0.34 points a year.

Waste rules are the third. They bite slowly. Site waste plans increasingly ask for fewer single-use poly sheets and for take-back of clean film; we remove 0.21 points for reduced consumption per square metre built.

How much does a roll of 6-mil poly or 15-mil under-slab construction film cost?

USD 96.39 to USD 105.41 buys a 20 by 100 foot roll of 6-mil clear construction film at US distributors, about USD 3.70 to USD 4.05 per kilogram. A 15-mil Class A under-slab roll lists at USD 549.33, or about USD 12.05 per kilogram.

Those are delivered distributor prices. Contracts pay less. A 2,000 square foot roll of 6-mil sheet weighs about 26.1 kilograms, so the Staples listing at USD 96.39 works out to USD 0.52 per square metre and the Airgas listing for Poly-America sheet at USD 105.41 to USD 0.57. The Stego listing for a 14 by 100 foot roll of 15-mil sheet equals USD 4.22 per square metre, eight times the 6-mil price per square metre, because it carries a premium resin blend and an ASTM E1745 Class A rating. Douglas Insights puts the 2025 global ex-works average for construction film at USD 2.44 per kilogram, about 0.66 times the lowest US distributor price, consistent with distribution, freight and retail margin adding roughly half again. The price leg grows 1.65% a year, taking the average to USD 2.87 per kilogram by 2035.

Which polyethylene film manufacturers supply construction film, and how concentrated are they?

Poly-America holds an estimated 6.8% share of 2025 construction film revenue and the top three suppliers 15.9%, by Douglas Insights estimates from plant footprint and product range. No leader reports construction film revenue separately, so every share here is modelled.

Poly-America of Grand Prairie, Texas, founded in 1976, describes itself on its company site as the world’s largest producer of polyethylene construction film, selling sheet from 1 foot to 40 feet wide and 0.3 to 10 mil thick from plants in Chester, South Carolina, Henderson, Nevada and Cottage Grove, Minnesota. It says 100% of its manufacturing scrap goes back into film. Amcor, since closing the Berry Global deal on 30 April 2025 as disclosed in its SEC exhibit, targets USD 260 million of pre-tax synergies in fiscal 2026; its Visqueen trading name, British Polythene Limited, sells damp proof membranes, gas protection and air and vapour control layers in the UK. Viaflex, formerly Raven Engineered Films and owned by Industrial Opportunity Partners, makes vapor and gas barrier films in Sioux Falls with about 450 employees. Stego Industries sells Stego Wrap, a 15-mil Class A under-slab sheet made in the US. Reef Industries of Houston makes Griffolyn reinforced polyethylene vapor retarders for roofs, walls, slabs and crawl spaces. Up North Plastics, part of the Poly-America group, adds agricultural film capacity.

Where does construction film tonnage grow fastest, Asia Pacific or the Gulf?

Asia Pacific leads with USD 6.64 billion, 38.2% of 2025 construction film revenue, and grows fastest at 5.71% a year to USD 11.56 billion by 2035. India and Southeast Asia offset the Chinese slump, since their housing and metro programmes still add slab area each year.

North America holds USD 4.27 billion and grows 4.12%, anchored by 1.36 million US housing starts and heavier under-slab specifications. Europe, at USD 3.80 billion, grows 3.63%; Eurostat reported on 19 February 2026 that average 2025 construction production rose 0.5% in the EU and was flat in the euro area. Latin America reaches USD 2.37 billion by 2035 at 5.08% as Brazilian and Mexican housing programmes expand. The Middle East and Africa, worth USD 1.22 billion, is the wildcard at 5.11%: Gulf giga-projects can add or remove whole container loads of construction film in a quarter.

Which standards set under-slab construction film grades, from ASTM E1745 to BBA certificates?

ASTM E1745 is the main grading standard for under-slab construction film in North America, with Class A the strongest grade; a 15-mil Class A sheet such as Stego Wrap lists a permeance below 0.01 perms. In the UK, Agrément certificates and Radon Council membership frame damp and gas membranes.

The standard matters for tonnage. Thicker sheet sells more resin. A Class A construction film at 15 mil uses 2.5 times the resin of 6-mil sheet per square metre, so specification upgrades add kilograms without adding floor area. Visqueen lists BBA, CE and Radon Council marks for its damp proof and gas protection range. Douglas Insights counts gas and radon membranes as a USD 1.69 billion segment in 2025, and damp proof membranes as USD 2.29 billion.

What if Chinese housing starts keep falling: which 2035 construction film value follows?

The 2035 construction film value spans USD 23.39 billion in the slower case to USD 32.27 billion in the faster case, around a USD 27.77 billion base. Chinese starts and US housing decide most of the gap, because housing alone carries 1.12 of the 3.10 volume points.

In the slower case, Chinese new starts fall again after the 20.4% drop that the statistics bureau reported for 2025, and US starts slip below 1.3 million, so construction film tonnage grows 1.90% a year. In the faster case, Indian and Gulf building accelerates and Class A sheet becomes standard under US slabs, lifting volume to 4.20%. Raising the volume rate by 1 point adds USD 2.81 billion to the 2035 construction film figure; cutting it by 1 point removes USD 2.58 billion. Ownership consolidation, such as the Amcor and Berry Global combination of 30 April 2025, sits in the price leg rather than the volume leg. Five published forecasts put construction film growth between 4.1% and 6.2% a year, and our 4.80% sits just below the middle of that band.

Douglas Exclusive: the Construction Film Demand Scorecard

The Construction Film Demand Scorecard is a Douglas Insights model, not an official index, built from 17 sourced inputs. Those are 3 Chinese floor-space counts, 4 US housing counts, 2 Eurostat output changes, 3 distributor prices and 5 published growth rates. It scores each region from 0 to 10 on stock, momentum and price.

North America wins. The finding is that North America, not Asia Pacific, scores highest for a construction film seller, at 21.2 of 30. Asia Pacific has the largest stock, 6.60 billion square metres of Chinese floor space under construction, but its momentum score is cut by the 20.4% fall in new starts. North America combines 1.36 million housing starts with the best price realisation, since 15-mil Class A sheet fetches USD 12.05 per kilogram at distribution. Europe scores lowest of the three large regions, at 16.7, because EU construction output rose only 0.5% in 2025.

Construction film methodology: how do 7.12 million tonnes and USD 2.44 per kilogram reconcile?

7.12 million tonnes multiplied by USD 2.44 per kilogram equals USD 17.37 billion in 2025, or exactly 7.12 billion kilograms times 2.44. Five regional models, five resin segments, five applications and three end uses each sum to that construction film total.

Tonnage grows 3.10% a year to 9.66 million tonnes; price grows 1.65% to USD 2.87 per kilogram. Combined, (1.031 x 1.0165) minus 1 gives 4.80% a year and USD 27.77 billion in 2035. Cross-check one: two published 2025 construction film sizes of USD 16.74 billion and USD 19.92 billion bracket ours, which sits 3.8% above the lower and 12.8% below the upper. Cross-check two: our ex-works average is 0.66 times the lowest US distributor price for 6-mil sheet. Cross-check three: our 4.80% CAGR sits inside the 4.1% to 6.2% published band. Countries with counted inputs: 3, the US, China and the EU-27 as one bloc.

Do residential, commercial or industrial and infrastructure sites buy more construction film?

Residential sites buy the most, USD 8.27 billion or 47.6% of 2025 construction film value, because every house needs a slab or crawl space sheet plus wall and roof underlay. Commercial sites take 29.9% and industrial and infrastructure sites 22.5%.

Commercial construction film, worth USD 5.19 billion, is weighted to protective sheeting and air and vapour control layers in offices, retail and hospitals. Industrial and infrastructure use, at USD 3.91 billion, is the heaviest per square metre, as 10-mil to 15-mil sheet goes under warehouse and data hall slabs. Residential use is the most price-sensitive: a builder chooses between USD 0.52 per square metre for 6-mil sheet and USD 4.22 for 15-mil Class A sheet.

What does moving from 6-mil to 15-mil construction film do to kilograms per slab?

Moving from 6-mil to 15-mil construction film raises resin use 2.5 times, from about 140 to 351 grams per square metre at a 0.92 density. That single specification change explains 0.71 of the 3.10 volume points in our model.

For a 2,000 square foot slab, 6-mil construction film weighs about 26.1 kilograms and 15-mil about 65.2 kilograms. The buyer pays more per square metre but less per kilogram of performance, since puncture and permeance ratings rise faster than weight. For a film extruder, heavier gauge is the cheapest growth available: no new jobsite, just more resin per roll.
