However, consumers will not open the express on the spot for larger items that are not easy to carry. Therefore, it is difficult to solve the recycling problem of all express packages by relying solely on the recycling desk. Therefore, enterprises have also begun to work hard on packaging materials to promote the use of this environmentally friendly green express packaging. Li Siwei, head of the Cainiao Yizhan in beijing university of chemical technology, said that the green express package is of very good quality and strong strength, and comes with a self-adhesive strip with a very clever design. Its biggest characteristic is that it is degradable and can be reused many times, reducing the use of adhesive tape, eliminating white pollution and having good quality in use.这是一个特殊年代的故事。这是一段人类改造自然利用自然的传奇。这是一部歌颂中国北部高原荒漠塞罕坝上老一代造林人奉献青春和生命的英雄史诗。上世纪六十年代初，为减少京津冀地区的风沙危害，国家指定由林业部和河北省在承德境内高原荒漠塞罕坝上建立机械林场，抵御浑善达克和科尔沁沙地南侵。以主人公冯程、覃雪梅等为代表的第一代造林人——来自全国18个省市的林业大中专毕业生与林业干部职工为骨干的369人开荒队伍，带领当地干部群众拉开了与自然抗争的序幕。岂料，因造林立地条件恶劣机械造林失败，转为人工造林。他们在平均海拔1500米、最低气温超过零下43度的环境下，在长达半个世纪的时光里，战严寒、斗酷暑、抛青春、洒热血，营造起“世界上最大的人工林海”，筑牢京津冀绿色生态屏障，拱卫京津冀蓝天，在荒凉的塞罕坝上，冯程和他的伙伴们同进退，共患难，也收获了友谊和爱情，谱写了壮丽的人生诗篇。Key points: Collect seedlings locally.
