In the packaging industry, “low-carbon” and “sustainability” have gradually become key concerns. Major brands are starting to improve the ecological friendliness of their final products through various aspects such as design, production, and selection of environmentally friendly materials.
At present, polylactic acid (PLA) non-woven fabric materials with good biodegradability and practical functionality are becoming a new popular packaging material. Specifically, the use of polylactic acid non-woven fabric as packaging material has the following characteristics:
Ecological friendliness
The ecological friendliness of polylactic acid fibers and non-woven fabrics can be manifested in three aspects: “bio based, biodegradable, and easy to recycle”.
Among them, polylactic acid fiber non-woven fabric products can be completely decomposed into carbon dioxide and water by microorganisms in natural environments with certain temperature and humidity, such as sand, silt, and seawater. Polylactic acid product waste can be completely decomposed into carbon dioxide and water under industrial composting conditions (temperature 58 ℃, humidity 98%, and microbial conditions) for 3-6 months; Landfilling in conventional environments can also achieve degradation within 3-5 years.
It should be noted that industrial composting of polylactic acid requires certain conditions to be achieved. As a packaging material, polylactic acid non-woven fabric products have a certain life cycle and good performance in conventional environments. Whether in diverse transportation environments such as land, rail, sea, and air, they can provide stable protection for the packaged goods.
Good mechanical performance
Polylactic acid non-woven fabric has good mechanical properties, with certain strength and good tear resistance, and can withstand certain pressure and impact. In practical applications, it can provide cushioning protection for packaged products.
Soft and scratch resistant
Polylactic acid fibers and non-woven fabrics also have good flexibility, which can provide good protection for packaged products in packaging applications, without damaging the paint surface and appearance, and without affecting subsequent sales and user experience.
Texture without shedding chips
Polylactic acid non-woven fabric packaging has a good texture, does not shed chips, can maintain the beauty of the product, and does not affect the sales experience.
Buffer and shock absorption
Polylactic acid fiber can not only be used for product packaging, but also made into PLA flakes, further providing cushioning and shock absorption protection for the product.
Natural materials can be used for food packaging
The raw material of polylactic acid fiber comes from renewable plant resources such as corn, potatoes, and crop straw. It has good biocompatibility, biodegradability, antibacterial properties, and breathability. It can be widely used in the packaging of various foods, drugs, and fresh products, such as fruit preservation, tea bags, coffee bags, and the manufacturing of other biological packaging materials.
Extinguish immediately upon leaving the fire, reduce smoke and be non-toxic
Polylactic acid fiber is not easy to burn, extinguishes immediately upon ignition, has no black smoke or toxic gas emissions, and has good safety in use.
Wide applicability
PLA fiber supports blending with other cellulose fibers (such as bamboo fiber, viscose fiber, etc.), which can not only reduce costs while maintaining the full degradability of packaging products, but also achieve rich functionality of packaging products and meet the needs of application scenarios.
In addition, polylactic acid fibers have strong adaptability and can be customized according to user needs, suitable for packaging requirements of various shapes and sizes.
Dongguan Liansheng Non woven Technology Co., Ltd. was established in May 2020. It is a large-scale non-woven fabric production enterprise integrating research and development, production, and sales. It can produce various colors of PP spunbond non-woven fabrics with a width of less than 3.2 meters from 9 grams to 300 grams.
