Use of blister tray:
Plastic tray is the most advantageous tool for loading, unloading, storage and transportation. If used in conjunction with forklift truck, it can greatly increase the efficiency of transportation and has a wide range of USES.
If the plastic tray stacking use, can increase the utilization rate of the warehouse, significantly reduce the cost. So it can be seen that in all the transport process, the small plastic tray role is very obvious.
Plastic tray according to the structure can be divided into: grid tian font plastic tray, sichuan font plastic tray, grid double-sided plastic tray, plate double-sided plastic tray, grid nine-foot plastic tray, plane nine-foot plastic tray, anti-moisture pad plastic tray, modular pad plastic tray, disposable export plastic tray.
Features of the blister tray:
1. PVC sheet material has high toughness and is not easy to burn. Chlorine gas will be generated when burning, which will have certain impact on the environment. PVC sheet is a kind of widely used and popular material, PVC film can be divided into two kinds of environmental protection and not environmental protection, can be made into a transparent, color, antistatic, gold-plated, flocking, etc all kinds of blister packaging products, the main characteristics of high transparency, good surface luster, crystal points less, small water lines, wide application, strong shock resistance, and easy to forming, the products are widely used in toys, food, electronics, medicine, electrical appliances, gifts, cosmetics, stationery, and other products packaging.
2, PS hard piece density is low, toughness is poor, easy to combustion, combustion will produce styrene gas (a harmful gas), so generally used to produce a variety of industrial blister tray. PS sheet material is a new environmental protection packaging material developed in recent years. With its excellent thermoforming performance, good environmental protection performance and health performance, it is widely used in medicine, food, toys and electronics.
Three, PET hard film good toughness, is a new material developed in recent years. With its excellent toughness, high strength, high transparency, and recycling, easy combustion, combustion does not produce harmful gas, belongs to environmental protection materials and gradually ban PVC, but the price is high. It is suitable for high-end blister products. The blister bubble shell in Europe and America generally requires PET material, but its high thermal melting point brings great difficulties to high-cycle packaging. In order to solve this problem, people compound a layer of PVC film on the surface of PET, named PETG, but the price is higher. Mainly used in electronics, food, toys, color box window, collar, footwear packaging. The advantages are as follows: 1. Excellent transparency and smoothness, good display effect. 2. Excellent surface decoration performance, can be printed without surface treatment, easy to press patterns, easy to metal treatment (vacuum gilding layer) 3. Good mechanical strength. 4. Good barrier performance to oxygen and water vapor. 5. Good chemical resistance, can withstand the erosion of a variety of chemical substances. 6. Non-toxic, reliable health performance, can be used to food, medicine and medical equipment packaging, and Y ray on the packaging of the items disinfection. 7. Good adaptability to environmental protection and economical and convenient recycling; When burning its wastes, it will not produce harmful substances to the environment. PET sheet is considered to be an ideal packaging material for environmental protection.
Iv. PETG sheet, also known as GPET sheet, is made of an amorphous PET resin modified by cyclohexanediol. The biggest advantage of PETG sheet is good thermal sealing performance, easy to operate when sealing, good sealing effect and easy glue bonding. At the same time, its chemical resistance, optical properties, resistance to line are also very good. PETG is approved by the FDA for food contact standards, and can be used in the packaging of food and personal health products, medical and health equipment, food and other fields, as well as the packaging of electronic devices. Its advantages are as follows: 1. Good transparency, suitable for products requiring high transparency. 3. Excellent machinability, which can be processed by saw, die cutting, drilling and laser cutting, cold bending and hot bending, bonding, welding and polishing, printing and painting; And cold bending does not whiten, beautiful appearance. 4, good thermal forming, no need for preheating can be formed, high precision, good deep forming, no cracking and uniform thickness. 5, low combustion, good fire resistance, non-combustion, low smoke, no harmful substances after combustion.
Five, PP sheet is made of PP resin through beer, pressing, cutting and other processes, with light weight, surface brightness and calm, heat resistance, high mechanical strength, excellent chemical stability and insulation, non-toxic and other characteristics, after heat molding can be made into beverage cups, food boxes and other daily necessities.
Six, GAG is a three - layer composite sheet. It is a three-layer composite sheet produced by co-extruding the middle layer APET and the upper and lower layers PETG in an appropriate proportion, which is especially suitable for packaging boxes that need to be bonded by high-frequency heat sealing and glue. Its advantages are as follows: 1. Good transparency, transparency can reach more than 90%, good texture, suitable for products requiring high transparency. 2, excellent impact strength and rigidity, hard and durable material, suitable for high impact strength applications. 3, good processing, can use saw, die cutting, drilling and laser cutting and other processing methods, but also cold bending and hot bending, bonding, welding and polishing, printing and coating; And cold bending does not whiten, beautiful appearance. 4. Good thermal forming performance, no need for preheating to form, high precision, shrinkage rate of about 0.5%; Good deep molding, no cracking and uniform thickness. 5, environmental protection, recyclable use does not pollute the environment. 6. Excellent food hygiene, made of PETG, can meet all major food regulations, such as FDA or BGA, suitable for food packaging and other purposes... 7, good fire resistance, no combustion, low smoke, no harmful substances after combustion.
