Types of Dalian Blown Film Machines
As a key plastic machinery manufacturing hub in Northeast China, Dalian boasts years of technical accumulation. Its blown film machines form a complete range of models for diverse sectors, serving packaging, agriculture, water conservancy, new material R&D and other industries. Classified by different criteria, they can precisely meet varied production demands.
1. Classification by Application & Film Material
This is the primary standard for customer selection.
(1) General Packaging Blown Film Machines
The mainstream product line, designed for LDPE and HDPE packaging films. Featuring precise thickness control with tolerances below industry norms, they produce bags for daily goods, food and express delivery. Some models integrate inline printing for combined film blowing and printing to boost output efficiency.
(2) Agricultural Special Blown Film Machines
Developed for northern farming demands, split into greenhouse film and mulch film units.
Conventional greenhouse film machines enable low-cost mass production. Functional versions add anti-fog, UV-resistant and heat-preserving formulas for cold-climate cultivation in Northeast and North China.
Mulch film equipment produces ultra-thin films under 0.008 mm for no-till farming. Local models support low-residue degradable film to comply with environmental regulations.
(3) Industrial Special Film Blown Film Machines
Cover geomembranes, stretch wrap films and barrier films.
Geomembrane machines adopt thick-wall extrusion, delivering tensile strength over 18 MPa for water seepage prevention and tunnel waterproofing.
High-speed stretch wrap lines achieve output above 300 meters per minute for industrial cargo wrapping.
2. Classification by Structure & Core Technology
Reflecting local technical upgrading advantages
(1) Single-layer Blown Film Machines
Compact, cost-effective and easy to operate for small-batch production and material trials. Mini bench-top versions suit labs with accurate formula control for new material research.
(2) Multi-layer Co-extrusion Blown Film Machines
Flagship products including 2-layer, 3-layer, 5-layer and higher stack models:
3-layer units for high-barrier food packaging, raising oxygen barrier performance by over 60% via composite plasticization layers.
5-layer lines for heavy-duty packaging capable of holding loads over 50 kg, ideal for chemical raw materials and frozen food.
Rotary die head machines with 360° rotating dies greatly improve thickness uniformity, suitable for wide films over 5 meters with high precision requirements.
(3) Intelligent Automatic Blown Film Machines
Equipped with PLC controllers, online thickness inspection and automatic thickness adjustment to minimize manual intervention. Built-in IoT ports enable remote production data monitoring and digital factory management.
3. Classification by Size Specifications
Small machines: Width ≤ 1000 mm, annual output below 500 tons, for small workshops and research institutes
Medium machines: Width 1000–3000 mm, annual output 500–2000 tons, the mainstream standard model
Large machines: Width ≥ 3000 mm, annual output over 2000 tons, for wide greenhouse films and heavy-duty geomembranes
Summary
Dalian supplies a full spectrum of blown film machine models from standard to customized high-end versions, with market-driven technical innovations. It provides critical equipment support for high-quality development of China’s plastics processing industry.
