真空包裝袋在我們日常中使用頻率是非常高的,很多的家庭都會采用真空包裝袋來包裝食品,以達到延長保質期的目的。真空袋的材質直接影響到其保鮮性能,接下來我們就來了解一下真空包裝袋的材質及特點。

Vacuum packaging bags are frequently used in our daily life. Many families will use vacuum packaging bags to package food in order to prolong the shelf life. The material of vacuum bag directly affects its preservation performance. Next, let's learn about the material and characteristics of vacuum packaging bag.

聚酯是由多元醇和多元酸縮聚而得的聚合物總稱。主要指聚對苯二甲酸乙二酯(PET),聚酯(PET)真空袋它是一種無色透明、有光澤的真空袋,是以聚對苯二甲酸乙二醇酯為原料,采用擠出法制成厚片,再經雙向拉伸制成的真空袋材料。真空包裝袋機械性能優良,剛性、硬度及韌性高,耐穿刺,耐摩擦,耐高溫和低溫,耐化學藥品性、耐油性、氣密性和保香性良好,是常用的阻透性復合真空袋基材之一。常用做蒸煮包裝的外層材料,印刷性能較好。

Polyester is the general name of polymers obtained by polycondensation of polyols and polyacid. It mainly refers to polyethylene terephthalate (PET) and polyester (PET) vacuum bag. It is a colorless, transparent and shiny vacuum bag. It is a vacuum bag material made of polyethylene terephthalate as raw material by extrusion and biaxial stretching. Vacuum packaging bag has excellent mechanical properties, high rigidity, hardness and toughness, puncture resistance, friction resistance, high and low temperature resistance, chemical resistance, oil resistance, air tightness and fragrance retention. It is one of the commonly used base materials of barrier composite vacuum bag. It is commonly used as the outer material of cooking packaging, with good printing performance.


尼龍(PA)真空袋是一種非常堅韌的真空包裝袋,透明性好,并具有良好的光澤,抗張強度、拉伸強度較高,還具有較好的耐熱性、耐寒性、耐油性和耐有溶劑性,耐磨性、耐穿刺性優良,且比較柔軟,阻氧性優良,適于包裝硬性物品,例如油膩性食品、肉制品、油炸食品、真空包裝食品、蒸煮食品等。在尼龍真空袋基礎上可衍生出更高性能的尼龍復合袋和多層共擠真空袋。

Nylon (PA) vacuum bag is a very tough vacuum packaging bag with good transparency, good luster, high tensile strength and tensile strength, good heat resistance, cold resistance, oil resistance and solvent resistance, excellent wear resistance and puncture resistance, soft ratio and excellent oxygen resistance. It is suitable for packaging hard goods, such as greasy food, meat products Fried food, vacuum packaged food, steamed food, etc. On the basis of nylon vacuum bag, higher performance nylon composite bag and multi-layer coextrusion vacuum bag can be derived.

真空袋:聚乙烯(polyethylene ,簡稱PE)是乙烯經聚合制得的一種熱塑性樹脂。透明較尼龍的低,聲音較脆,具有優良的阻氣、阻油和保香性能。不適用高溫與冷藏使用,價格較尼龍的要便宜一些。一般用于沒有特殊要求的普通真空袋材質。

Vacuum bag: Polyethylene (PE) is a thermoplastic resin prepared by polymerization of ethylene. The transparency is lower than that of nylon, and the sound is crisp. It has excellent gas resistance, oil resistance and fragrance retention properties. It is not suitable for high temperature and cold storage. The price is cheaper than that of nylon. It is generally used for ordinary vacuum bag materials without special requirements.

鋁塑復合真空包裝袋(PET/AL/PE 或 PET/NY/AL/PE 或 PET/NY/AL/CPP),主要成分為鋁箔,不透明,呈銀白色,有反光澤,具有良好的阻隔性、熱封性,遮旋光性、耐高溫、耐低溫、耐油性、保香性;柔軟性等特點。適用于化學原料、醫藥中間體的防潮、避光、真空包裝。多采用四層結構,具有良好的隔水、隔氧功能。鋁箔真空袋在食品,電子,化工等行業中廣泛使用。

Aluminum plastic composite vacuum packaging bag (PET / Al / PE or PET / NY / Al / PE or PET / NY / Al / CPP), mainly composed of aluminum foil, opaque, silvery white, anti gloss, good barrier, heat sealing, optical opacity, high temperature, low temperature, oil resistance and fragrance retention; Flexibility and other characteristics. It is suitable for moisture-proof, light proof and vacuum packaging of chemical raw materials and pharmaceutical intermediates. Four layer structure is adopted, which has good water and oxygen separation functions. Aluminum foil vacuum bag is widely used in food, electronics, chemical and other industries.
