As the core equipment in packaging, printing and material processing, paper roll die cutting machine realizes precise shaping of paper or material by die-cutting, indentation and hot stamping. It has a wide range of applications and a wide variety of materials. The following is an analysis of typical application scenarios and material characteristics:
1.Paper materials
Common Document:
Application scenarios: Daily packaging of labels, notes, envelopes, paper boxes, etc.
Characteristics compatibility: Weight range is generally 60-300g/m2. The die-cutting machine can be adjusted by adjusting the pressure parameters to meet the cutting requirements of tissue paper (such as label paper) and thick cardstock (such as gift boxes packaging).
Process advantages: Die cutter can accurately cut complex shape (such as irregular label), embossing process to ensure that the carton fold without cracks.
Corrugated paper:
Application scenarios: Express Box, logistics packaging, display stands.
Characteristics compatibility: Die cutters need to be equipped with high-hardness die cutters (such as steel knives) to handle the corrugated fiber layer and corrugated core structure to avoid burrs or crushing during cutting.
Process advantages: through the pre-embossing process, the the corrugated paper can maintain structural strength during folding, and can be cut out of the handle holes, ventilation holes and other functional openings.
Specialized paper:
Application scenarios: art paper, pearlescent paper, laser paper and other high-end packaging materials.
Characteristics compatibility: Low voltage die-cutting techniques are required to avoid damage to paper surface coating (such as the pearlescent layer or laser film) and to ensure alignment of patterns through precise positioning system.
Process advantages: die die-cutting and hot stamping processes, can accurately form a metal luster pattern, enhance the visual effects of packaging.
2.Thin Film
Plastic film:
Application Scenarios: Food packaging bags, Medical aluminum foil packaging, Soft Packaging of Daily Department Stores.
Characteristics Compatibility: Die cutters need to be equipped with heating die-cutters to soften the thermoplastic film (e.g. PE, polypropylene) to avoid adhesion or wire drawing during cutting.
Process Advantages: By adjusting the temperature and cutting speed of the hot knife, continuous die-cutting of the film can be achieved, and the indentation process ensures that the packaging bag is easy to tear.
Compound membrane:
Application scenarios: Multi-layer composite packaging (such as aluminum plastic composite film, paper plastic composite film).
Characteristics compatibility: High-precision die-cutting systems are required to ensure that different material layers (e.g. aluminum foil, plastic, paper) are cut at the same time, avoiding layer separation or fraying of edges.
Process advantages: The combination of die-cutting and punching processes makes functional processing of composite films possible, such as breathable holes and rip-able openings.
3. Metal Foil Materials
Aluminum Foil:
Application Scenarios: Drug blister packaging, food cling film, battery tabs.
Characteristics Compatibility: Die cutters need to be equipped with hard alloy die cutters (such as tungsten steel knives) to deal with the high hardness and ductility of aluminum foil and to avoid metal chips or deformation during cutting.
Process advantages: The precision of aluminum foil die-cutting size ≤ ±0.1mm is ensured by precise positioning systems to meet the requirement of automatic packaging lines.
Copper foil:
Application scenarios: Circuit boards, flexible electronic components.
Characteristics compatibility: Ultraprecision die-cutting techniques (such as laser die-cutting or rotary die-cutting) are required to avoid burrs or damage the conductive layer during cutting and to ensure stable circuit performance.
Process advantages: the combination of die cutting and etching process, can be processed for high-density circuit design of copper foil microstructure.
4. Non-woven materials
Nonwoven:
Application scenarios: Medical masks, wet wipe packaging, disposable hygiene products.
Characteristics compatibility: Die cutting machine needs to be equipped with an ultrasonic die-cutting system. Through high frequency vibration, the nonwoven fiber melts, avoiding the burr or fiber fracture caused by traditional knife cutting.
Process Advantages: Ultrasonic die-cutting can achieve continuous, high-speed cutting of non-woven fabric. indentation process ensures the stability of the folding structure of the mask.
Meltblown fabric:
Application scenarios: Air filtration materials, Medical Protective Suit.
Characteristics compatibility: Low voltage die-cutting technology is required to avoid damage to the fiber structure of molten fabric and to ensure that filtration performance is not affected.
Process Advantages: The combination of die cutting and laminating process enables the meltblown fabric and non-woven cloth to be laminated, improving filtration efficiency.
5 .Other special materials
Leather:
Application scenarios: Shoe materials, luggage, car interiors, etc.
Characteristics compatibility: Die cutters need to be equipped with a high hardness die cutter (such as a steel knives) to deal with the toughness of the leather, while embossing allows the leather to form a three-dimensional shape (such as a crease in the vamp).
Process advantages: Die cutting and hot stamping process can be combined to achieve leather surface metal luster pattern processing.
Rubber:
Application scenarios: Sealing rings, shock absorbers, button.
Characteristics compatibility: Low temperature die-cutting technique is needed to avoid rubber stabbing or deformation during cutting, and precise positioning system is used to ensure accuracy of die-cutting dimensions.
Process advantages: Die cutting and punching processes can be combined to realize the functional opening of rubber products (such as button contacts).
