    • A plastic fastening device that includes a recycled material. In one embodiment, at least a portion of the fastening device includes a blend of two or more thermoplastic resins, at least one of which is a recycled material. The blend may include, for example, a fresh thermoplastic resin and a recycled thermoplastic resin. The fresh thermoplastic resin may include, for example, one or more of a polyethylene (PE), a polyamide (PA), or a polycarbonate (PC). The recycled thermoplastic resin may include, for example, a recycled polyethylene terephthalate (rPET). In a preferred embodiment, the blend of two or more thermoplastic resins includes a blend of (i) rPET and (ii) one of a low-density polyethylene (LDPE), a LDPE/LLDPE (linear low-density polyethylene) blend and LLDPE, (iii) wherein the rPET constitutes about 88% to 98% of the total material content and the LDPE, the LDPE/LLDPE blend, or the LLDPE constitutes the balance.
    • 包括再循环材料的塑料紧固装置。 在一个实施方案中,紧固装置的至少一部分包括两种或多种热塑性树脂的共混物,其中至少一种是再循环材料。 共混物可以包括例如新鲜的热塑性树脂和再循环的热塑性树脂。 新鲜的热塑性树脂可以包括例如聚乙烯(PE),聚酰胺(PA)或聚碳酸酯(PC)中的一种或多种。 回收的热塑性树脂可以包括例如回收的聚对苯二甲酸乙二醇酯(rPET)。 在一个优选的实施方案中,两种或多种热塑性树脂的共混物包括(i)rPET和(ii)低密度聚乙烯(LDPE),LDPE / LLDPE(线性低密度聚乙烯)共混物和LLDPE ,(iii)其中rPET构成总材料含量的约88%至98%,LDPE,LDPE / LLDPE共混物或LLDPE构成余量。
