The Zeal X corrugated bubble envelopes bags are all made of paper materials, less consumables in mass production, high strength and stiffness, and light weight. Inside is a W-shaped corrugated paper with superior cushioning. By changing the thickness and gram weight of the core paper, the corrugated liner envelope bag can obtain different strength and stiffness. The envelope is free from contamination during production, and can be recycled and easily disposed of. The reinforced sides of our mail envelopes ensure that they do not tear or crack during packaging or transit, and the pouch is opaque, protecting items from direct sunlight and dust. Corrugated bubble mailer bags are an environmentally friendly alternative to traditional plastic buffer packaging, ensuring that your goods are not damaged during transportation.
