Description
Features of 0.5mm PP thermoforming sheet in roll
Rouleau de feuille PP materials are generally selected brand of Feuille de PP resin, usually used in vacuum molding is a total of PP sheet resin and modified PP sheet materials.The modified PP sheet material mainly focuses on improving the molding process performance, transparency and heat resistance, etc. The main modification has the following aspects.
A. Improve the molding performance of Rouleau de feuille PP
In order to improve the properties of Feuille de PP, the most commonly used method is to use polyethylene (PE) to modify Feuille de PP. Mixing a small amount of (20% ~ 30%) low density polyethylene (PE) in Feuille de PP, can make Feuille de PP melting property narrow, easy to flow when the sheet heating defects can be improved, can use the ordinary vacuum molding process.Of course, the addition of polyethylene will also bring some negative effects on the performance, such as rigidity and heat resistance to a certain degree of decline in the application of hollow to be considered.
B. Improve the transparency of Rouleau de feuille PP and its molding products
Adding nucleating agent (transparent agent) to Rouleau de feuille PP is an effective way to improve the transparency of Rouleau de feuille PP and its products.After the nucleating agent is added, a large number of fine crystals will be produced in the production of Rouleau de feuille PP, which will reduce or even avoid the production of large spherulites. The reduction or elimination of large spherulites will obviously improve the transparency of Feuille de PP. At the same time, due to the action of nucleating agent, the formation of a large number of fine crystals, so that the cleanliness of Feuille de PP.The rigidity of Feuille de PP was improved while the transparency of Feuille de PP rouler was improved.
C. Improve the heat resistance and rigidity of Rouleau de feuille PP
The heat resistance and rigidity of PP sheet can be improved obviously by means of filling modification.The most widely used fillers are talc powder, calcium carbonate, etc.By adding 30% ~ 40% talc powder, the rigidity of Rouleau de feuille PP can be improved obviously, and the temperature can be raised to over 140℃. Meanwhile, the excellent sanitary performance and better oil resistance of pure PP sheet can be maintained, and the price is relatively low.Its molding products can be used for microwave heating.
Specification Of 0.5mm PP thermoforming sheet in roll
Rouleau de feuille PP has excellent electrical insulation performance, especially good high-frequency insulation, high breakdown voltage strength, and low water absorption, which can be used for heat resistant insulation materials used at 120 ℃.
PP sheet vacuum molding conditions
In the vacuum blister molding process, the best molding performance of modified Rouleau de feuille PP with (20% ~ 30%) low density polyethylene (PE) is obtained.
According to the requirements of Rouleau de feuille PP to the forming conditions, the Angle of mold release: punch 2 o ~ 3 o(5 o optimally), die 1o ~ 3 o(5 o optimally);Molding temperature: sheet temperature 150 ~ 180℃, mold temperature 70℃ ~ 90℃;Molding shrinkage: punch 0.02 ~ 0.03mm/mm, die 0.03 ~ 0.04mm /mm.Because PP sheet material sheet material has the characteristics of abundant material source, low price, non-toxic, tasteless, good transparency, high mechanical strength, so Feuille de PP material sheet material for vacuum molding processing, made of various packaging products are widely used in food, medicine, mechanical parts, daily necessities and other packaging.At present, PP packaging products appear on the market, in addition to simple lunch box, water, spoon, bowl, pickles box, a variety of local special products packaging box, yogurt pot, tray, etc. Also widely into the market.PP sheet products can be heated in microwave oven and sterilized at 125℃, so it is widely used in ready-to-eat food packaging.In addition, PP sheet vacuum blister molding products have been gradually applied in agricultural production in recent years, such as seedling tray, breeding cup, etc.
The bonding problem is the same as PE, which can be bonded after pretreatment.Welding with heating plate and friction welding was very successful.
Post-processing: when stamping by punching die and trimming die, the cutting gap needs 5mm, the material temperature is too high, the cutting burr. There should be corresponding measures to keep the minimum deformation amount during sealing. The heat sealing with coating layer, the temperature is 150 ~ 180℃, and the sealing time is 1s.
