封箱膠帶
又稱之為bopp膠帶、包裝膠帶等，它是以BOPP雙向拉伸聚丙烯薄膜為基材，經過加溫均勻涂抹壓敏膠乳液，使其形成8μm----28μm不等的膠層，是輕工業類企業、公司、個人生活中不可缺少的用品，國家對膠帶行業還沒有一個完善的標準，只有一個行業標準《QB/T 2422-1998封箱用BOPP壓敏膠粘帶》 把BOPP原膜經過高壓電暈處理后，一面表面形成粗糙，在將膠水涂在上面，先形成母卷，再通過分條機分切成規格不等的小卷，就是我們日常使用的膠帶了。壓敏膠乳液，主要成分是丁酯。
特性
瞬時膠粘力--封箱膠帶即粘即牢。
固定能力--即使只用很小的壓力，也能按照您的想法粘固在工件上。
容易撕斷--容易從帶卷上撕下， 而不會有膠帶拉伸和拖拉的現象。
有控制的展開--封箱膠帶能以一種有控制的方式拉離帶卷，既不太松，又不太緊。
柔順性--封箱膠帶能方便地適應急變的曲線形狀。
薄型--封箱膠帶帶不會留下厚的邊緣堆積物。
平滑性--封箱膠帶摸上去很平滑，用手按壓時不會刺激手。
抗轉移--封箱膠帶揭除后不會留下膠粘劑。
抗溶劑--封箱膠帶的背材有阻止溶劑滲透。
抗碎裂--封箱膠帶不會出現裂片。
抗回縮--封箱膠帶能沿曲線表面伸展而不會出現回縮脫開現象。
抗剝離--油漆會緊緊固著在封箱膠帶的背材上。
厚度薄，性能價格比好· 外觀透明，雙面粘· 無毒、無味、安全性好· 使用方便，效率高· 抗緩沖強度高· 良好的回縮率· 抗刺穿· 防撕裂性能好。
Packing tape
Known as bopp tape, packing tape, etc., it is with bopp two-way stretch polypropylene film as the backing material, through heat evenly daub emulsion pressure sensitive adhesive, make its form 8 microns - 28 mu m range protectionlayer, middle class is light industry enterprises, companies, personal life indispensable things, to tape industry has not been a perfect standard, only an industry standard QB/T 2422-1998 with bopp sealing pressure sensitive adhesive tape, the bopp film after dealing with the high voltage corona, one side surface is rough, the glue on it, to form a mother first, then by slitting machine cutting into range specifications of small volume, is our daily use of adhesive tape. Emulsion pressure sensitive adhesive, the main ingredient is butyl ester.
features
Instantaneous - packing tape that stick the adhesive force.
Fixed capacity - even if only a small pressure, can also according to your idea cementation on the workpiece.
Easy tear - off from the coil, and there will be no tape stretched and delay phenomenon.
Can have control -- packing tape in a controlled manner to pull away from the coil, neither too loose nor too tight.
Flexibility - packing tape can easily adapt to snap the shape of the curve.
Thin - packing tape with don't leave the edge of the thick accumulation.
Smooth - packing tape very smooth to the touch, hand by hand press without stimulation.
After transfer resistance - packing tape jie in addition to not leave adhesive.
Resistance to solvent - packing tape on the back of material have prevent solvent penetration.
Resistance to fracture, packing tape won't appear lobes.
Resistance to bounce back - packing tape can stretch along the curve surface and won't bounce back off.
Anti stripping - paint will firmly fixation on packing tape on the back of material.
Thin thickness, good cost performance, transparent appearance, double-sided adhesive, non-toxic, tasteless, good safety, convenience, high efficiency, the buffer strength high, good retraction rate, puncture resistance, laceration resistant performance is good.
