方便袋是一種使用廣泛的包裝袋，主要生產(chǎn)工藝是吹塑，吹塑工藝的質(zhì)量直接影響到后續(xù)的制造環(huán)節(jié)，因此吹塑效果非常重要。吹塑的作用是將塑料顆粒制成塑料薄膜，然后由制袋機進行進一步加工切割，制成我們常見的方便袋。下面是方便袋吹塑的大致過程：

Convenience bags are a widely used packaging bag, and the main production process is blow molding. The quality of the blow molding process directly affects the subsequent manufacturing process, so the blow molding effect is very important. The function of blow molding is to make plastic particles into plastic films, which are then further processed and cut by a bag making machine to make our common convenient bags. The following is the general process of blow molding convenience bags:

吹塑是將塑料顆粒通過吹塑機吹成塑料薄膜。這個過程是將塑料顆粒倒入吹塑機的進料口，加熱材料，使其融化成一個熔體。將熔融塑料在螺桿擠出機中定量擠出，然后通過口膜成型，壓縮空氣注入到型腔中，再通過風(fēng)環(huán)吹冷卻。被拖拉機以一定的速度牽引后，由卷揚機卷成一卷。吹制后進一步加工，得到各種方便袋。

Blow molding is the process of blowing plastic particles into a plastic film through a blow molding machine. This process involves pouring plastic particles into the feed port of the blow molding machine, heating the material to melt it into a melt. Molten plastic is quantitatively extruded in a screw extruder, then molded through a mouth film, compressed air is injected into the mold cavity, and then cooled by an air ring blowing. After being pulled by the tractor at a certain speed, it is winded into a roll by the winch. After blowing, further processing is carried out to obtain various convenient bags.

1.原材料制備：濟南方便袋的主要原材料是聚乙烯（PE），其次是聚丙烯（PP），這兩種材料需要進行配料、混合、熔融等預(yù)處理過程。

1. Preparation of raw materials: The main raw material for Jinan convenience bags is polyethylene (PE), followed by polypropylene (PP). These two materials require pre-treatment processes such as batching, mixing, and melting.

2.注塑成型：將預(yù)處理好的原料注入吹塑機的料斗中，然后通過加熱和壓力，使原料熔融并流入吹塑模具中。

2. Injection molding: Inject pre processed raw materials into the hopper of the blow molding machine, and then melt the raw materials and flow into the blow molding mold through heating and pressure.

3.吹塑成型：在模具內(nèi)加入高壓氣源，將模具內(nèi)的熔融塑料擠出，并根據(jù)模具的形狀進行吹塑成型。

3. Blow molding: Add a high-pressure air source to the mold, extrude the molten plastic inside the mold, and perform blow molding according to the shape of the mold.

4.冷卻成型：吹塑成型完成后，方便袋需要進行冷卻成型，使其結(jié)構(gòu)更加穩(wěn)定。

4. Cooling forming: After the completion of blow molding, the convenience bag needs to be cooled and formed to make its structure more stable.

5.印刷、裁剪、封口：根據(jù)客戶要求和生產(chǎn)需求，對成型的方便袋進行印刷、裁剪和封口等后續(xù)處理。

5. Printing, cutting, and sealing: According to customer requirements and production needs, the formed convenience bags are printed, cut, and sealed for subsequent processing.

6.檢查合格后裝箱：品質(zhì)檢驗合格后，將方便袋裝入指定的包裝箱中，并進行包裝、碼垛等處理。

6. Packing after passing the inspection: After passing the quality inspection, the convenience bag will be placed in the designated packaging box and processed for packaging, stacking, etc.

總之，方便袋的吹塑成型是一個比較復(fù)雜的過程，需要相應(yīng)的生產(chǎn)經(jīng)驗和技術(shù)支持，才能生產(chǎn)出質(zhì)量穩(wěn)定、成型精度高的方便袋產(chǎn)品。更多相關(guān)內(nèi)容就來我們的網(wǎng)站http://glhxsd.com咨詢！

In short, the blow molding of convenience bags is a relatively complex process that requires corresponding production experience and technical support in order to produce stable quality and high molding accuracy convenience bag products.
