Can customized PLA coated bamboo pulp paper become the mainstream material for green packaging in the future?

1. Basic advantages of bamboo pulp paper: toughness of natural fibers
The raw material of bamboo pulp paper comes from bamboo. As a fast-growing natural plant, bamboo pulp paper has high fiber strength. Compared with traditional wood pulp paper, bamboo pulp paper has more slender and tough fibers, so it performs well in strength and wear resistance. Bamboo pulp paper has better tear resistance and durability, and can better protect packaged items during daily transportation, storage, etc., and reduce damage caused by external forces.
In contrast, the fiber structure of traditional wood pulp paper is relatively loose, which makes it more prone to deformation and cracking when subjected to pressure, friction or other external forces. Especially when exposed to humid or greasy environments for a long time, ordinary wood pulp paper is prone to softening and breakage, which is undoubtedly a major defect for packaging materials.

2. PLA coating improves paper strength and durability
On the basis of bamboo pulp paper, the addition of coating materials greatly improves its physical properties. Among them, the use of PLA (polylactic acid) coating is undoubtedly the key. PLA is a bio-based material fermented from plants, which has a good surface strength improvement effect. When PLA coating is applied to the surface of bamboo pulp paper, it not only makes the surface of the paper smoother, but also significantly enhances the tear resistance, water resistance and oil resistance of the paper. These enhanced properties make customized PLA coated bamboo pulp paper a more durable and adaptable packaging material for a variety of environments.
PLA coating can effectively prevent the softening and deformation of paper when exposed to humid or high-moisture environments for a long time. Ordinary paper is easily softened and even cracked in a humid environment due to moisture. However, PLA coated bamboo pulp paper can effectively prevent moisture penetration, maintain its strength and structural stability, and extend the service life of packaging materials. Especially in the field of food packaging, the improvement of water resistance and oil resistance makes this material an ideal choice.

3. Improve tear resistance: cope with long-term transportation and storage
In logistics and supply chains, packaging materials often need to go through transportation, storage and other processes, and withstand long-term friction, collision and extrusion. Custom PLA coated bamboo pulp paper performs particularly well in this regard. Due to the presence of PLA coating, the tear resistance of bamboo pulp paper has been greatly enhanced, and it can withstand large external force collisions during daily transportation and storage without being easily damaged.
This advantage is particularly important because the damage of packaging materials will not only affect the safety of the product, but may also bring additional costs and losses to the company. In contrast, ordinary paper is prone to cracks or damage when encountering impact and pressure, especially under high pressure. Therefore, the durability of customized PLA coated bamboo pulp paper makes it the preferred packaging material for many commodities that need to be transported and stored for a long time.

4. Oil resistance and environmental protection performance: provide protection for green packaging
As consumers' demand for green environmental protection continues to increase, the market demand for packaging materials with environmental protection performance is also continuing to rise. Customized PLA coated bamboo pulp paper has become an important choice in the field of green packaging due to its excellent environmental protection performance. PLA, as a biodegradable material extracted from plants, can not only degrade into carbon dioxide and water, but also effectively reduce the burden of traditional plastic packaging on the environment.
In addition to environmental protection, PLA coated bamboo pulp paper also has obvious advantages in oil resistance. In many food packaging scenarios, oil penetration is a major challenge facing packaging materials. PLA coating can effectively prevent grease from penetrating into the paper, maintaining the integrity and cleanliness of the packaging material. This feature makes customized PLA coated bamboo pulp paper particularly widely used in the catering, food and other industries.
