自封袋指的是壓合就可以自動封口的包裝袋，常見的有夾鏈自封袋，吹骨（凹凸骨）自封袋等。下面來看看濟南自封袋的彈性強度以及相應(yīng)分類。

Self-sealing bag refers to the packaging bag that can be automatically sealed after pressing. The common ones are chain clamping self-sealing bag, bone blowing (concave-convex bone) self-sealing bag, etc. Let's look at the elastic strength and corresponding classification of Jinan self-sealing bags.

自封袋的彈性強度

Elastic strength of self-sealing bag

自封袋聚氨酯熱彈性體有較高的撕裂強度，通?？蛇_天然橡膠10倍。但耐高溫性能鉸差，作環(huán)境溫度高于能就有所下降。電性能方面，由于聚氨酪熱彈性體具有一定的親水特性能，吸收空氣小的水分而位絕緣性下降．在高絕緣場合中使用受到限制熱塑性彈性體除亡述外二烯之類。在大多數(shù)情況下，成注塑的制的原材料都用全新料。但對于一些使用要求不高的制品，人們往往來用再生原料進行注塑生產(chǎn)。這一方面可以降低成本；另一方面可以實現(xiàn)塑料材料的循環(huán)利用。

Self-sealing polyurethane thermal elastomer has high tear strength, usually up to 10 times of natural rubber. However, the high temperature resistance is poor, and the working environment temperature is higher than the energy. In terms of electrical properties, polyurethane thermoplastic elastomer has certain hydrophilicity, which absorbs small amount of water in the air and reduces its insulation. The use of thermoplastic elastomer in high insulation occasions is limited, except for isoprene. In most cases, the raw materials for injection molding are all new materials. But for some products with low use requirements, people often use recycled raw materials for injection molding. On the one hand, it can reduce costs; On the other hand, it can realize the recycling of plastic materials.

自封袋的相應(yīng)分類

Corresponding classification of self-sealing bags

塑料自封袋又稱為密實袋、骨袋、密封袋。自封袋按其材質(zhì)分類，通例為PE吹塑自封袋跟復(fù)合材料貼骨自封袋。

Plastic self-sealing bags are also known as compact bags, bone bags and sealing bags. Self-sealing bags are classified according to their materials. The common example is PE blow-molded self-sealing bags and composite bone-attached self-sealing bags.

PE自封袋其材料以聚乙烯（LDPE）制成的一種密封袋，是一種綠色產(chǎn)品,堅韌耐用、可重復(fù)利用、可印花廣告、嘜頭、可做冰箱保鮮袋，利用期長。主要用于產(chǎn)品包裝,存放食品、飾品、藥品、化妝品、冷凍食品、郵品等等,防潮、防水、防蟲、防止貨色散落，起演繹作用,給買家整齊尺度的形象，而且還可能重復(fù)利用,微微一按便會密封的嚴嚴實實的，無味，柔韌性好，封合隨意，非常方便。其優(yōu)點是低廉，用途廣泛。

PE self-sealing bag is a kind of sealed bag made of polyethylene (LDPE). It is a green product, tough and durable, reusable, printable advertising, shipping marks, and can be used as a refrigerator fresh-keeping bag with a long service life. It is mainly used for product packaging, storing food, jewelry, medicine, cosmetics, frozen food, postal products, etc. It is moisture-proof, waterproof, insect-proof, and can prevent goods from scattering. It plays a deductive role, giving buyers a neat image, and may also be reused. It will be sealed tightly, non-toxic, tasteless, flexible, and convenient. Its advantages are low price and wide use.

復(fù)合貼骨自封袋，其也是PE自封袋產(chǎn)品特點嫁接到復(fù)合材料，達到方便，快捷等特點。指塑料袋、鋁箔袋、尼龍袋、屏蔽袋等，在袋口放兩根塑料骨條，經(jīng)過機器熱壓而粘合牢固，可重復(fù)密封及開口，個別適用于電子元器件、IC，PCB、LED等產(chǎn)品包裝。

The composite bone-attached self-sealing bag, which is also the characteristics of PE self-sealing bag product, is grafted to the composite material to achieve convenient, fast and other characteristics. It refers to plastic bags, aluminum foil bags, nylon bags, shielding bags, etc., where two plastic bone strips are placed at the mouth of the bag, which are firmly bonded after machine hot pressing, and can be repeatedly sealed and opened. It is applicable to the packaging of electronic components, IC, PCB, LED and other products.
