為了保證硬化塑料薄膜的質(zhì)量,需要通過(guò)印刷、復(fù)合等工序進(jìn)行處理。印刷技術(shù)將塑料薄膜從原始的透明和無(wú)色狀態(tài)轉(zhuǎn)變?yōu)榫哂卸喾N圖案和字體的印刷薄膜。印刷方法一般采用凸版印刷和膠印印刷。這些濟(jì)南塑料包裝袋印刷方法具有圖案清晰、獨(dú)特、使用方便的特點(diǎn)。復(fù)合工藝將塑料薄膜的兩面貼合在合適的材料上,可以提高塑料薄膜的強(qiáng)度和耐磨性,減少塑料對(duì)外部物質(zhì)滲透的影響。

In order to ensure the quality of hardened plastic film, it needs to be processed through printing, lamination and other processes. Printing technology transforms plastic films from their original transparent and colorless state into printed films with multiple patterns and fonts. The printing methods generally use relief printing and offset printing. These Jinan plastic packaging bag printing methods have the characteristics of clear patterns, uniqueness, and easy use. Composite technology involves bonding both sides of plastic film onto suitable materials, which can improve the strength and wear resistance of the plastic film and reduce the impact of plastic on external material penetration.

其次,待印刷和復(fù)合膜需要進(jìn)一步加工成各種包裝袋。制袋機(jī)是一種通過(guò)獨(dú)特的機(jī)械將塑料薄膜切割成制袋所需形狀的設(shè)備。有不同類(lèi)型的塑料袋,如邊緣密封、底部密封、黑色底部密封、穿孔袋和平面袋。不同類(lèi)型的袋子可以通過(guò)不同的加工方法實(shí)現(xiàn),生產(chǎn)的昆明塑料包裝袋可以滿(mǎn)足各種包裝要求。

Secondly, the printed and composite films need to be further processed into various packaging bags. A bag making machine is a device that uses unique machinery to cut plastic film into the desired shape for bag making. There are different types of plastic bags, such as edge sealed, bottom sealed, black bottom sealed, perforated bags, and flat bags. Different types of bags can be processed using different methods, and the Kunming plastic packaging bags produced can meet various packaging requirements.

然后,塑料包裝袋必須經(jīng)過(guò)后續(xù)技術(shù)處理和測(cè)試,以確保產(chǎn)品合格。加強(qiáng)驗(yàn)證的過(guò)程包括對(duì)塑料袋的尺寸、容量、重量、抗壓性和耐撕裂性進(jìn)行強(qiáng)度測(cè)試。昆明塑料包裝袋制作產(chǎn)品合格后,將包裝好的塑料袋運(yùn)到市場(chǎng)上銷(xiāo)售或與其他生產(chǎn)合作。

Then, the plastic packaging bags must undergo subsequent technical processing and testing to ensure product qualification. The process of strengthening verification includes conducting strength tests on the size, capacity, weight, compression resistance, and tear resistance of plastic bags. After the Kunming plastic packaging bag production products are qualified, the packaged plastic bags will be transported to the market for sale or cooperation with other production partners.
