OPA/AL/PVC laminated foil

Component Materials of OPA/AL/PVClaminated foil:

  1. OPA (Oriented Polyamide, Polyamide, Nylon) layer:

– CHARACTERISTICS: The OPA layer provides good mechanical strength and puncture resistance, as well as excellent gas and water vapor barrier properties.

– Application: This material is usually used for packaging that requires high strength and durability, and can effectively protect the food inside from the external environment.

  1. AL (Aluminum Foil) layer:

– Characteristics: Aluminum foil layer has excellent barrier properties, which can effectively isolate light, oxygen and moisture, preventing oxidation and spoilage of food. As an intermediate layer, it provides excellent barrier performance to ensure the freshness and safety of the contents.

– Application: Aluminum foil layer is commonly used to package food products that are susceptible to oxidation, such as dried fruits, coffee, spices, etc.

  1. PVC (Polyvinyl Chloride) layer:

– Characteristics: PVC layer provides good sealing, molding, heat sealing performance, softness, high transparency, and is usually used in the outer layer of packaging to increase the stability of the structure.

– APPLICATIONS: PVC layers are commonly used in bags, blister packs, etc. to provide additional protection and aesthetics.

Production process of OPA/AL/PVC laminated foil:

– Co-extrusion: Different materials are extruded simultaneously through a multi-layer co-extruder to form a multi-layer structure.

– Laminating: Different materials are laminated together by adhesives or other methods to form composite materials.

– Printing and Coating: Printing and coating as needed to increase the aesthetics and functionality of the package.

Advantages of OPA/AL/PVC laminated foils:

– Excellent barrier properties: this composite material effectively blocks moisture, oxygen and light, extending the shelf life of food products.

– Good mechanical properties: combining the advantages of the different materials, it has a high resistance to tearing and puncture, making it suitable for a wide range of packaging formats.

– Good heat sealing properties: ensures that the package is hermetically sealed and prevents leakage.

– Suitable for a wide range of packaging needs, from simple bagging to complex multi-layer packaging

– Versatility: suitable for a wide range of food packaging, but also can be used in other areas such as pharmaceuticals and cosmetics.

– Customizability: Different combinations of thickness and structure are possible according to customers’ needs.

Application areas of OPA/AL/PVC laminated foil:

– Food Packaging: Used for packaging cookies, candies, nuts, coffee and other foods to maintain the freshness and taste of the food.

– Pharmaceutical packaging: used for packaging tablets, capsules, liquid drugs, etc., to ensure the stability and effectiveness of drugs.

– Cosmetic Packaging: Used for packaging skin care products, perfume, etc. to prevent product deterioration and pollution.

– Others: also used for packaging of medical supplies, electronic components and other fields.

When using OPA/AL/PVC laminated foil, you need to make sure that the material complies with food safety standards, especially in applications that come into direct contact with food, to ensure that no harmful substances are released.

Differences between PS and CTP base plate

图片
With the increasing maturity and the rapid development of CTP technology, as well as the declining of price, CTP technology has been more and more welcomed by the majority of printing practitioners, usage of CTP plates have the potential trend to catch up with the traditional PS plate. The overall requirements of the printing plate is very high, especially the current CTP plate is mostly used for high-grade color printing plate, to ensure the quality of the plate, the plate based apparent quality is the premise. The characteristic of CTP technology is the quality of CTP based plate, such as the apparent quality, physical property and electrolytic performance. The aluminum plate base is widely used according to CTP plate technical requirement. The difference between CTP plates and PS plate on the apparent properties of aluminum plate base are as follows. The basic appearance requirements of the aluminum base plate is clean and smooth, no cracks, corrosion pits, air vents, scratches,

Introduction of aluminum foil insulation material

图片
Aluminum foil insulation material is the best thermal insulation material at present in the world. It has the advantages of light weight, low thermal conductivity, good heat resistance, aging resistance, easy combustion with other substrates, bonding does not produce droplet and other excellent properties. On the application, it is widely used in building roofing, wall, ceiling, floor, doors and windows as insulation materials. Aluminum foil itself is a good conductor of heat, directly used basically has no heat insulation, but accelerate the heat loss, so when used the insulation cotton is wrapped inside the aluminum foil . It has the functions of heat insulation, waterproof, moisture-proof and so on. Its solar radiation absorption coefficient is very low, which can insulate most of the heat transfer. Introduction of advantages of aluminum foil insulation material: (1) Simplification of structure to avoid waste. (2) It is unnecessary to set roof exhaust system. (3) Waterproof lay
