塑料袋在日常生活中似乎司空見(jiàn)慣，它常見(jiàn)得好像讓大家都不是特別關(guān)注它是怎么生產(chǎn)的。Plastic bags seem to be commonplace in daily life, as they s

白點(diǎn)氣泡：①干燥不充分White spot bubbles: ① Insufficient drying②上膠量不足：督辦、復(fù)溶性差、轉(zhuǎn)移率下降。。 薄膜太厚② Insufficient glue application: poor supervision, poor solubility, and decreased transfer rate Thin film too thick③復(fù)合后膠未流平：膠分子量大、熟化不夠，復(fù)合熱輥溫度太低、氣溫較低而預(yù)熱輥沒(méi)用③ After compounding, the glue is not leveled: the molecular weight of the glue is large

食物包裝：近年來(lái)，米面粉等食物包裝逐步采用編織袋包裝。經(jīng)常見(jiàn)的編織袋有：面粉編織袋大米編織袋玉米編織袋等編織袋Food packaging: In recent years, woven bags have gradually been used for food packaging such as rice flour Common woven bags include flour woven bags, rice woven bags, corn woven bags, and other woven bags蔬菜等農(nóng)業(yè)物品包裝,再后替代紙制水泥包裝袋 當(dāng)前,因?yàn)槌善焚Y本和價(jià)錢問(wèn)題,我國(guó)每年有60億條

塑料袋制作的輕量化，因?yàn)楝F(xiàn)在國(guó)內(nèi)塑料袋制作越來(lái)越青睞輕量化的材料了，幾乎每一種塑料袋的包裝都在外形跟結(jié)構(gòu)上都很強(qiáng)調(diào)了這一點(diǎn)，塑料袋制作后的輕量化包裝還可以繼續(xù)保持原先包裝的性能跟功能，這對(duì)輕量化包裝材

方便袋生產(chǎn)的背后，往往與環(huán)境保護(hù)相互矛盾。傳統(tǒng)的方便袋生產(chǎn)過(guò)程中，會(huì)消耗大量的資源和能源，同時(shí)還會(huì)產(chǎn)生大量的廢棄物，對(duì)環(huán)境造成極大的污染。然而，隨著科技的不斷進(jìn)步，新型的方便袋逐漸走入人們的視野，為解決這一問(wèn)題提供了新的思路。The production of convenience bags often contradicts environmental protection The traditional production process of convenience bags consumes a large amount of resources and energy,

塑料膠袋是我們?nèi)粘Ｉ钪惺褂脼閺V泛的包裝袋，但它的密封性和滲透性卻是我們需要考慮的兩個(gè)重要因素。密封性是指膠袋內(nèi)外空氣無(wú)法交換，從而達(dá)到保鮮、防潮、防塵、防蟲(chóng)等作用。而滲透性則是指氣體或液體通過(guò)膠袋的能力，如果膠袋的滲透性較高，則其保鮮效果會(huì)受到影響。Plastic bags are widely used packaging bags in our daily lives, but their sealing and permeability are two important factors that we need to consider Sealing

復(fù)合袋的材質(zhì)是聚對(duì)苯二甲酸乙二醇酯與高壓聚乙烯，習(xí)慣簡(jiǎn)寫(xiě)為PET PE復(fù)合袋，其具有透明度高，阻氧性好的特點(diǎn)，所以特別適合象面包和蛋糕類食品的充氣包裝。而且由于這種復(fù)合膜的耐熱和耐寒性也都很好，也可以作為速凍食品和蒸煮食品的包裝袋。The material of the composite bag is polyethylene terephthalate and high-pressure polyethylene, commonly abbreviated as PET PE composite bag It has the characteristics of high transparen
