High Speed Stretch Film Line

High speed Stretch Film Line
High speed stretch film line is full automatic cast extrusion production equipment specially for manufacturing LLDPE pallet stretch wrap film, hand stretch film and jumbo roll machine grade stretch film. The complete production line integrates raw material feeding, plasticizing extrusion, die head casting, cooling forming, online thickness inspection, edge trimming, automatic winding and waste recycling into one continuous automated workflow. Driven by frequency conversion motor and controlled by PLC centralized system, this production unit runs steadily at high continuous speed to produce uniform thickness stretch film with good stretchability, puncture resistance and stable self adhesion. It fits large scale packaging material factories for mass production of machine pallet wrap film, hand stretch film and agricultural wrapping film, helping manufacturers improve daily output, reduce raw material waste and lower comprehensive production cost.

Core Advantages
High Production Capacity to Boost Daily Output
Optimized screw plasticizing structure and large cooling roller unit support stable high speed continuous running. Automatic non stop turret winding avoids frequent machine shutdown for roll replacement, greatly lifting daily finished jumbo roll output compared with conventional low speed stretch film equipment.
Precise Thickness Control Reduces Raw Material Waste
Online real time thickness monitoring cooperates with automatic die head fine adjustment system to keep film thickness fluctuation within tiny range. Uniform finished film effectively avoids excessive raw material consumption caused by uneven thick or thin layer, lowering material cost and improving finished product pass rate.
Excellent Film Physical Performance
Scientific screw plasticizing and gradual cooling technology guarantee finished stretch film with high pre stretch rate, strong puncture resistance and consistent single side self adhesion. Produced film meets standard quality requirement for automatic pallet wrapping machine and manual wrapping usage.

Flexible Formula and Specification Adjustment
Operators adjust extrusion temperature, line running speed and additive proportion via touch screen to switch between thin hand stretch film and thick machine grade stretch film quickly. Compatible with anti UV masterbatch and anti static additive to produce functional customized stretch film.
why choose us
1. Cut comprehensive manufacturing cost in long term
High finished yield rate and waste recycling design save large amount of LLDPE raw material; fewer workers cut daily labor expenditure; high speed output lowers unit production cost of finished stretch film and improves overall profit margin.
2. Diversified products expand market sales range
One production line can produce hand wrap film, machine pallet stretch film and customized functional film, enabling factories to supply multiple packaging clients and reduce market operation risk relying on single product.
3. Stable equipment operation reduces downtime loss
Heavy duty machine frame and well known brand core electrical components lower equipment failure rate, ensure long time non stop continuous production and avoid economic loss from unexpected production halt.
4. Flexible customized configuration for different factory demand
Support personalized adjustment on line width, extruder specification and auxiliary functional unit according to customer factory workshop space, target daily output and main product orientation.
5. Complete after sales technical service
Supplier provides on site installation, equipment debugging, worker operation training and long term remote technical guidance to help customers quickly put production line into formal mass production.
