With the continuous deepening of the concept of sustainable development, reducing the use of traditional plastics has become a common goal for society. Against this backdrop, polylactic acid (PLA), an environmentally friendly material that can be biodegraded, has gradually attracted attention. PLA is derived from starch extracted from plants such as corn and sugarcane, and has relatively minor environmental impacts. It is widely regarded as one of the key materials for achieving sustainable development goal.
The common garbage bags and shopping bags in the market are predominantly composed of BPAT + PLA composite materials，available in colors such as white, semi-transparent, black, or green, with designs including flat bags, vest bags, and self-adhesive bags. To further align with environmental protection requirements and enhance packaging functionality, Jointhope specially launched 100% biodegradable PLA series products, including biodegradable single-track zippers, multi-track zippers and child safety zippers, etc. These zippers, serving as accessories, effectively support paper packaging and eco-friendly plastic packaging solutions, addressing sealing challenges while expanding packaging options.
In addition, Jointhope pack also offers high transparency fully biobased and degradable PLA bags for packaging (suitable for fruit and vegetable packaging, disposable beverage bags, etc.) as well as PLA vacuum sealing bags. Due to its high transparency and can clearly display the contents of the packaging. They are ideal alternatives to traditional OPP, PE and PET materials. In the meanwhile, our company has developed double-layer structure paper-plastic bags (PLA/Paper) and double-layer high barrier PLA aluminum-plastic bags. The PLA aluminum-plastic bags have excellent oxygen barrier properties and water barrier properties, achieving high barrier effects, and can be fully degraded under composting conditions, making them ideal alternatives for packaging tea, coffee and pet food.
Under composting conditions, polylactic acid (PLA) bags can be fully decomposed into carbon dioxide, water, and organic fertilizer within approximately 180 days. However, in natural environments, their degradation rate is significantly influenced by temperature and humidity. Consequently, when selecting degradable packaging, it is advisable to conduct a thorough evaluation based on specific product requirements to identify the most appropriate solution for practical application scenarios.
