With the combination of steam knife coating, scraper coating, sizing equipment, and other diversified and multi-functional equipment, we achieve different coating implementations of a variety of schemes. Our state-of-the-art manufacturing and printing processes results in a product that is biodegradable, repulpable, and compostable - and safe for people of all ages.
Why Leafpak Stands Out
With our unique coating technology and advanced equipment, we are able to offer products with higher quality oil and water resistance and heat-sealing properties than other biodegradable brands in the market.
We know that the environment and mother nature are hurt by the food and beverage industry's use of unsustainable packaging. But there is also a big health danger it imposes to each person who uses those types of products! BPAs, phthalates, and perfluoroalkyl chemicals are also dangerous additives to standard food packaging - and they're linked to developmental or reproductive harm, or cancer.
Our key end product, and the result of this revolutionary technology and science, is the oil-proof board (OPB). The board naturally matches the final use of the high-quality packaging that requires barrier properties. OPB uses a fluorine-free oil repellent and is in line with EC, FDA, and GB9685 regulations along with being fluoride-free, plastic, silica-free, and mineral wax free. On top of that, it's safe to use in your microwave!
The Paper Making Process
The Paper Making Process Explained
First we start with Timber, like fir, birch, and spruce. Components of wood include lignin (25%), cellulose (50%) and hemicellulose (25%). Timber is de-barked and sent through a chipping machine to start the pulping process.
Chemical pulping includes heat and pressure in caustic soda and sulfur (50-60% fiber yield). Mechanical pulping includes hot water or grindstones (>89% fiber yield)
The hydrapulper agitates the wood fibers to create pulp mass resembling thick porridge.
The pump mass is placed in a blend chest, and numerous chemicals and dyes are added to color the paper. If the pulp is made of recyled paper, and was dyed before, it will go through a de-inking process before the chest.
After dyes, fibers are de-clustered to increase surface area and improve fiber bonding.
Then, it goes through a screening and cleaning process which removes undesirable fibrous and non-fibrous materials.
Lastly, it is put through a papermaking machine! The effluent waste water from the pulp is treated and recycled.
