Blown Film Manufacturers in China | Top Suppliers
China has become a major sourcing base for blown film used in flexible packaging, industrial protection, agriculture, construction, and logistics. Buyers can compare suppliers producing LDPE, LLDPE, HDPE, multilayer PE, high-barrier coextrusions, shrink film, and tubular film.
Blown film extrusion melts polymer through a circular die, inflates a controlled bubble, cools the tube, and winds it into rolls. Film performance depends on resin selection, layer design, gauge control, cooling, corona treatment, winding quality, and production discipline.
An experienced supplier should translate the end use into measurable specifications. Important details include thickness and tolerance, lay-flat or finished width, roll diameter, core size, coefficient of friction, seal window, puncture resistance, optical properties, additives, treatment side, and compliance documents.
China’s manufacturing base covers simple monolayer films and advanced three-layer and multilayer structures. Suitable options range from bags and liners to laminated sealant webs, thermoforming films, greenhouse covers, shrink bundling, stretch hoods, and recyclable mono-PE packaging.
Before selecting a manufacturer, send the packed product, converting process, machine speed, dimensions, annual demand, destination market, required tests, and current failure points. A capable supplier can then recommend a structure, prepare samples, define acceptance criteria, and plan repeat export supply.

Qingdao Cloud Film Packaging Materials Co.,Ltd.
-
No. 269 Zhengyang Road, Chengyang District, Qingdao City, Shandong Province, China
Qingdao Cloud Film Packaging Materials Co., Ltd., known as CloudFilm, is a Chinese blown film manufacturer and export supplier serving converters, importers, brand owners, and industrial users. Its broader flexible-packaging background helps buyers compare structure and application—not only unit price.
CloudFilm operates six PE blown-film lines with annual capacity of approximately 5,000 tonnes. Production covers customized LDPE, LLDPE, and blended PE films, including clear, white, black, and functional grades for bags, liners, protection, agriculture, and secondary packaging.
Buyers can specify thickness, width, roll length, 3- or 6-inch cores, corona treatment, additives, winding, and export packing. The portfolio connects LDPE film, tough LLDPE film, PE shrink film, PE protective film, and stretch hood film through one supplier.
CloudFilm also supports coextruded structures in which the skins, mechanical core, and seal side perform different jobs. For oxygen-sensitive or puncture-prone packs, buyers can review PE/PA/PE film and related multilayer options before requesting a trial.
For recyclable packaging development, MDO PE film can be evaluated with PE-rich sealant structures. CloudFilm can review an existing sample or TDS, prepare sheets or trial rolls where available, discuss acceptance tests, and coordinate repeat international shipments.
For a useful proposal, send the application, current structure, thickness, width, roll format, printing or lamination process, sealing conditions, destination market, and estimated volume when you contact CloudFilm.
Changxi Packaging Technology (Yixing) Co., Ltd.
-
No. 18, Wushuang Road, Zhangzhu Town, Yixing City, Jiangsu Province, China 214231
Changxi Packaging is a multilayer blown film manufacturer focused on coextruded high-barrier and functional packaging. Its public product range includes five-, seven-, and nine-layer structures using PA, PE, PP, tie layers, and EVOH for demanding food and thermoforming applications.
The company reports four multilayer coextrusion lines, high-cleanliness workshops, slitting and bag-making equipment, and annual capacity up to 10,000 tonnes. This supplier profile is most relevant when barrier, puncture resistance, forming behavior, or specialized layer design drives the project.
Jiangyin Shuanghui Plastic Packaging Co., Ltd. — Jiangyin Shuanghui
-
No. 92, Huayuan West Road, Huayuan Village, Changjing Town, Jiangyin City, Jiangsu Province, China
Jiangyin Shuanghui develops and produces multilayer coextruded and functional films, including HDPE, LDPE, high-barrier packaging films, biodegradable films, and converted bags. The supplier suits buyers who want roll film and downstream bag formats coordinated within one manufacturing program.
Its positioning is practical for industrial liners, heavy-duty packaging, special-purpose PE films, and projects requiring cutting, sealing, or bag conversion after extrusion. Buyers should confirm the exact resin system, barrier target, dimensions, test methods, and current production availability before sampling.
Henan Tianfeng Biotech Co., Ltd. — TIAN FENG
-
No. 1, Tianguan Avenue, Wancheng District, Nanyang City, Henan Province, China
TIAN FENG focuses on custom PE blown film for agricultural covering, construction protection, warehousing, furniture protection, and industrial use. Its portfolio includes greenhouse film, mulch film, building film, pallet covers, liners, stretch film, and custom-colored or printed products.
This supplier profile is strongest where wide film, outdoor function, color, folding style, bag geometry, or private-label packing matters. Buyers should define UV exposure, climate, service life, optical or thermal function, installation method, thickness tolerance, roll format, and disposal route.
Huangshan Yuandian New Material Science and Technology Co., Ltd. — Yuandian
-
No. 46, Yongxin 1st Road, Chengbei Industrial Park, Huizhou District, Huangshan City, Anhui Province, China
Yuandian concentrates on stretch hood film, heavy-duty packaging, stretch wrap, and barrier packaging solutions. Its profile is relevant to resin, building-material, appliance, paper, and industrial-product shippers that need load containment, puncture resistance, outdoor protection, and consistent automatic hooding.
For evaluation, buyers should send the pallet dimensions, load height, weight, corner profile, hooder model, film circumference, target thickness, stretch ratio, holding force, outdoor exposure, printing requirement, and transport test. A full pallet trial is more informative than film data alone.
