在禮盒包裝之,中內托的作用非常重要,不僅能起到固定產品、保護產品的作用,還能襯托整個包裝更加美觀,下面食品包裝禮盒廠家就給大家介紹一下定制廠家常用三種內托材質區別。
In gift box packaging, the role of inner lining is very important. It can not only fix products and protect products, but also foil the whole packaging more beautiful. Below, food packaging gift box manufacturers will introduce the differences of three kinds of inner lining materials commonly used by custom manufacturers.
珍珠棉
Pearl cotton
EPE(ExpandablePolyethylene),是可發性聚乙烯。是非交聯閉孔結構,它是以低密度聚乙烯(LDPE)為主要原料擠壓生成的高泡沫聚乙烯制品,它是由低密度聚乙烯脂經物理發泡產生無數的獨立氣泡構成。
EPE (expandable polyethylene) is expandable polyethylene. It is a non crosslinked closed cell structure. It is a high foam polyethylene product extruded with low-density polyethylene (LDPE) as the main raw material. It is composed of countless independent bubbles generated by physical foaming of low-density polyethylene grease.
克服了普通發泡膠易碎、變形、回復性差的缺點。具有隔水防潮、防震、隔音、保溫、可塑性能佳、韌性強、循環再造、環保、抗撞力強等諸多優點。在禮盒生產廠家,珍珠棉可以跟各種色彩的絨布搭配在一起,讓禮盒更加出彩。
It overcomes the shortcomings of ordinary styrofoam, such as fragility, deformation and poor recoverability. It has many advantages, such as water-proof and moisture-proof, shockproof, sound insulation, heat preservation, good plasticity, strong toughness, recycling, environmental protection, strong impact resistance and so on. In gift box manufacturers, pearl cotton can be matched with various colored flannels to make the gift box more colorful.
海綿
Sponge
大都是由多異氰酸酯和多元醇作原料來合成的,基本反應是多元醇與多異氰酸酯生產聚氨酯的反應,常用的海綿學名叫聚氨酯軟發泡橡膠,聚氨酯是生活中常見的一種高分子材料,廣泛應用于制作各種“海綿”制品。海綿因其擁有較好的回彈性,所以常使用于玩具禮盒、電子產品包裝之中。
Most of them are synthesized from polyisocyanates and polyols. The basic reaction is the reaction between polyols and polyisocyanates to produce polyurethane. The commonly used spongy science is called polyurethane soft foaming rubber. Polyurethane is a common polymer material in life, which is widely used to make various "sponge" products. Because of its good resilience, sponge is often used in toy gift boxes and electronic product packaging.
食品包裝禮盒
EVA
EVA
是由乙烯(E)和乙酸乙烯(VA)共聚而制得簡稱為EVA。EVA的特點是具有良好的柔軟性,橡膠般的彈性,在-50℃下仍能夠具有較好的可撓性,透明性和表面光澤性好,化學穩定性良好,抗老化和耐臭氧強度好,無毒性。
It is prepared by copolymerization of ethylene (E) and vinyl acetate (VA), which is called EVA for short. EVA is characterized by good softness, rubber like elasticity, good flexibility at -50 ℃, good transparency and surface gloss, good chemical stability, good anti-aging and ozone resistance, and non-toxic.
珍珠棉、海綿、EVA三者的區別主要有以下幾點:
The main differences among pearl cotton, sponge and EVA are as follows:
1.用肉眼可以區別,海綿的話很有彈性,相對來說比這三者要輕。EVA的話有點硬硬的,一般是黑色,是三者里面較重的。EPE珍珠棉一般都是白色和黑色的,跟海綿很好區分,海綿不管你隨便怎么按都分恢復原狀,而EPE珍珠棉沒有回彈性,假若你使勁按下去按的地方會凹下去的狀態。
1. It can be distinguished with the naked eye that sponges are very elastic and relatively lighter than the three. EVA is a little hard, usually black, which is the heavier of the three. EPE pearl cotton is generally white and black, which is very different from sponge. The sponge will be restored to its original state no matter how you press it, but EPE pearl cotton has no elasticity. If you press it hard, the place where you press it will be concave.
2.EPE珍珠棉有波浪紋的,看上去有很多泡沫沾在一起,很輕。EVA是實體形的,有分濃度是多少的,相比之下較重。
2. EPE pearl cotton has wavy lines, which looks like a lot of foam sticking together, very light. EVA is solid, and its component concentration is relatively heavy.
