1. Applicable Plastic Film Types
Each plastic film has unique surface properties and printing characteristics, requiring targeted machine parameter settings and configurations.
PE Film
PE (including LDPE, LLDPE and HDPE) is a mainstream flexible packaging material with great flexibility, water resistance and heat sealability, suitable for food bags, shopping bags, daily chemical pouches and industrial packaging. Most PE films feature low surface tension, resulting in poor natural ink adhesion. Matched with high-precision tension control and corona treatment,stack flexo printing machine effectively enhance ink adhesion and ensure stable high-speed printing on PE substrates.
PP Film
PP film offers high transparency, heat resistance and mechanical strength, widely used in food packaging, daily goods packaging and labels, with mainstream types including BOPP and CPP. Through optimized printing pressure, professional ink matching and stable tension regulation, stack flexo printing machines achieve high-definition, color-consistent printing for PP films, meeting high end packaging aesthetic and quality requirements.
CPP Film
CPP (Cast Polypropylene) boasts superior heat sealability, transparency and flexibility, mainly serving as the inner functional layer for food and composite packaging. Its printing process requires strict surface treatment and ink compatibility control to adapt to subsequent lamination processes. Custom stack flexographic printing machine configurations stabilize printing quality and guarantee qualified post-processing performance.
PET Film
PET film features outstanding mechanical strength, dimensional stability and heat resistance, ideal for food, beverage and high-grade composite packaging. With more stable physical properties than PE and PP, PET requires matched ink formulas and precise printing parameters. Stack flexo printing machine realize high-precision multi-color printing and stable register accuracy for long term mass production of PET films.
2.Why Can Stack-Type Flexographic Presses Print Plastic Films?
Stack type flexo printing machine adopt independent modular printing units to support multi-color continuous production, adapting to plastic films of different widths and thicknesses. Its core advantages for plastic film printing are summarized as follows:
Precision Tension Control
Plastic films are prone to stretching, wrinkling and deviation under unstable tension. The high-precision tension control system ensures flat film operation and accurate overprinting throughout continuous production.
Effective Corona Treatment System
PE, PP and CPP have low surface energy that weakens ink adhesion. Corona treatment improves film surface activity, significantly enhancing ink wetting and bonding firmness.
Flexible Multi-color Printing
The press can be configured with 4, 6, 8 or more color groups to print logos, patterns, text and barcodes, adapting to packaging patterns of different complexity levels.
Matched Ink & Drying System
Custom ink formulas and targeted drying schemes ensure thorough ink curing, zero excessive residual solvent, and fully meet subsequent lamination and bag-making process standards.
Stable High Register Accuracy
Optimized mechanical structure and real-time register correction reduce color deviation, delivering consistent, delicate printing results for mass production.

3. How to Select a Stack Type Flexo Priting Machine for PE, PP, CPP and PET Films?
Uniform machine configuration cannot fit all plastic films. Buyers should clarify these production parameters in advance:
1.Confirm substrate type:Distinguish among PE, LDPE, LLDPE, HDPE, PP, BOPP, CPP and PET. Each substrate sets distinct requirements for tension, corona treatment and ink compatibility.
2.Confirm film thickness:Film thickness exerts great influence over running stability and tension settings. Ultra-thin substrates demand higher-precision tension control.
3.Confirm printing colours:Determine 4-colour, 6-colour, 8-colour or other layouts according to packaging artwork. More printing colours raise standards for register stability and drying capacity.
4.Confirm target production speed:For long-term continuous high-volume production, prioritise overall performance of unwinding, traction, tension, drying and rewinding assemblies.
5.Confirm downstream converting processes:If lamination or bag making follows printing, evaluate ink adhesion, solvent residue and compatibility between substrates and post-print workflows.

4. Application of Stack Type Flexo Priting machine for Plastic Film Printing
Benefiting from broad material adaptability and flexible multi-colour printing capacity, stack type flexo printing machine produce numerous flexible packaging items.
In food packaging, they process snack pouches, frozen food packages, vacuum packaging, condiment sachets and pet food bags.
Within daily-chemical sector, applications cover laundry detergent pouches, cleaning product packaging, wet-wipe packs and personal-care product wrappers.
For industrial packaging, the press handles chemical product packages, agricultural produce wrappers, fertiliser bags and diverse plastic pouches.
For projects requiring double-sided printing on plastic films, stack flexo printing machine support custom double-sided printing structures to lift material utilisation and operational flexibility.

5. Advantages of Stack Flexo Priting Machine for Plastic Film Printing
Compared with traditional printing technologies, flexo printing delivers high throughput, wide material compatibility and seamless roll-toroll continuous production.
For PE, PP, CPP, PET and other plastic films, stack flexo printing machines can be optimised for substrate characteristics to balance print quality and production efficiency.
Furthermore, stack-style layout brings remarkable operational flexibility, well suited for small-batch and medium-batch flexible packaging orders with frequent product change-overs. Proper automation configurations shorten job change-over and setup time for manufacturers running diverse SKUs.
6. Choose a Professional Stack Flexo Priting Machine Manufacturer
Successful plastic film printing relies not merely on the press itself. Film substrates, ink selection, corona treatment, printing plates, running speed and process parameters all play vital roles.
When sourcing stack type flexo printing machine, share full details with manufacturers: substrate types, thickness range, printing web width, number of colours, target running speed and end-use applications. Reliable manufacturers recommend well-matched machine structures and configurations based on real-world production needs, instead of simply selling presses by colour quantity or maximum speed.
For packaging factories printing mixed substrates including PE, PP, BOPP, CPP and PET, well-tailored configurations enhance material compatibility, printing stability and production efficiency, while reserving room for future product portfolio expansion.
