Model PC0 to make Cross pre-cuts on moving film at customizable distances

General Description

The PC0 is a motorised transverse (cross-cut) pre-cut unit designed to be installed as a host module on moving-film production lines (extruders, slitters, printing machines, welding machines, etc.).
Its primary task is to make controlled pre-cuts (partial or full) across the width of a continuous film web, for purposes such as easy-tear features on bags, shoppers, labels, and other flexible packaging formats.

Typical Applications

• Addition of tear-strip or easy-open features to packaging films (bags, garbage bags, shoppers) by pre-cutting the film before final converting.

• Pre-cutting webs in multi-material or laminate films, biodegradable films, non-woven webs where controlled partial cuts are needed.

• Retrofit installation into existing converting lines to provide pre-cut functionality without major overhaul.

Model PC200 to make Cross pre-cuts on moving film at customizable distances

General Description

The PC200 is a motorised pre-cutting machine designed for transverse (cross-cut) pre-cuts of moving web films. It is intended to be integrated as a unit into converting lines (extruders, slitters, bag-making machines, printing lines, welders, etc.) and is capable of handling a wide variety of film and sheet materials with customisable width.
It enables “easy-tear” or partial cut features (for example in bags, shoppers, labels) by pre-cutting moving film webs without fully severing them.

The unit is designed to be placed inline: the film web arrives, passes between the blade roller and the support roller; when the two rollers are pneumatically engaged, the blade roller plunges (to an adjustable depth) into the film material to create the pre-cut while the support roller backs the film.

The PC200 is capable of processing a broad range of materials, including but not limited to:

• PP (Polypropylene), PET, PVC, LDPE, HDPE, BOPP, CPP, laminated films, compostable/biodegradable films.

• Leather, eco-leather, synthetic leather, non-woven materials, Tyvek, foam, raffia, paper, multilayer paper, single-use table mats, labels.

Summary

In short, the PC200 is a high-speed, synchronised transverse pre-cut unit for moving film webs, offering flexibility (material types, adjustable cut spacing & depth), Industry 4.0-enabled control, and integration friendly design. It supports up to about 200 m/min (depending on material) and minimal cut spacing of 60 mm.

Our Pre Cut Machine Models - Longitudinal cut

Model PC-BP Longitudinal Cutting Machine for cutting at customizable distances

The PC‑BP is a motorized longitudinal pre‑cutting unit designed to perform precise partial cuts along the direction of the film web travel. It is intended for inline integration into film converting and processing lines such as extruders, slitters, printing machines, laminators, or welding units. The unit allows continuous production of longitudinal pre‑cuts without stopping the web, making it suitable for high‑speed industrial applications.

The PC‑BP is equipped with a blade roller featuring interchangeable circular blades and a pneumatically actuated support roller, which provides backing during the cutting process. The penetration depth of the blades is fully adjustable via micrometric screws, enabling operators to control the cut depth with high precision, from shallow tear lines to deeper partial cuts, while maintaining the integrity of the web.

How Does a Pre Cut Machine Work?

Working Principle of Pre-Cut Machines

Pre-cut machines create controlled cuts in continuous web materials like film, paper, or nonwovens — ideal for easy-open packaging, bag production, and roll converting.

1. Web Feed & Control:
The moving web passes through tension and guiding systems to ensure perfect alignment and stable speed.

2. Cutting Station:
Rotary shafts equipped with precision circular blades perform the cutting. The web runs between the blades and a backup (contrast) roller for clean, accurate cuts.

3. Cutting Types:

• Longitudinal Pre-Cut: Multiple blades slit the web lengthwise into narrower lanes or create easy-tear lines.

• Cross Pre-Cut: Circular blades make short transverse micro-cuts for controlled tearing or easy opening.

4. Integration:
Pre-cut modules can be seamlessly installed in existing production or converting lines, synchronized with line speed and registration sensors for exact positioning.

5. Precision & Quality:
Micrometric blade adjustment and servo control ensure consistent cut depth, repeatability, and minimal material stress — key for high-speed packaging and converting applications.

Advantages of Pre Cut Machines

Key Benefits of Blade Pre-Cut Technology

• Precision Cutting: Consistent, high-quality cuts with micrometric adjustment for different materials and thicknesses.

• Higher Production Efficiency: Continuous, in-line operation minimizes manual handling and boosts throughput.

• Improved Product Usability: Creates easy-open or tear-assist features that enhance the end-user experience.

• Material Savings: Optimized cutting patterns reduce waste and maximize usable web area.

• Reduced Downtime: Durable blades and quick-change designs enable fast maintenance and setup.

• Customization Flexibility: Configurable blade types, spacing, and cutting depth adapt to specific products and production needs.

Applications of our Pre Cut Machines

Typical Applications

Blade pre-cut systems are used across many packaging and converting industries to improve functionality and efficiency:

• Breathable Films: Create fine slits or micro-cuts to control air permeability for hygiene, medical, or agricultural films.

• Easy-Tear Packaging: Add controlled tear lines in bags, pouches, and sachets for effortless opening.

• Net Packaging for Fruit & Vegetables: Pre-cut plastic or mesh webs for clean, uniform bag production.

• Garbage Bags with Easy-Open Function: Integrate tear-assist cuts or pre-scored lines for quick separation and convenience.

• Retail Shoppers & Carry Bags: Produce consistent tear lines or handle perforations for automated bag conversion.

• Labels, Tags & Tear-Off Solutions: Precise pre-cuts simplify detachment of individual labels, coupons, or ticket sections.
