Luminy(r) PLA coated paper has emerged as a viable solution for transparent and demanding applications. Moreover, it offers a 75% reduction in the carbon footprint of its production. In addition, it can help to divert organic waste from landfills.
Several studies have been conducted to determine the cradle to gate effects of PLA production. This study aims to identify and quantify the most important environmental aspects of the entire PLA production chain. The findings show that energy consumption is the main contributor to this impact.
One of the most efficient ways to produce bio-based polymers is through the implementation of new technologies. For example, inorganic nanoparticles have been reported to improve the viscosity of PLA. However, this effect is not well understood. Moreover, there are a number of challenges and knowledge gaps to be addressed before bio-based polymers can take off.
While energy consumption is the most obvious, there are a few other key aspects. For instance, how much water do the various steps in the PLA production process require? Generally, most of the water used is recycled. Furthermore, the biomaterial storage approach estimates CO2 fixation in pla bags.
Similarly, the amount of energy used during the manufacturing process is also considered. A number of factors, such as the type of solvent and the concentration of the nucleophile, play a role in this.
PLA vs PE
The simplest way to explain PLA is that it is a biodegradable and renewable form of plastic. It's also a very cost effective material. Unlike PE, it can be produced using the same infrastructure that makes PE, and thus is a sustainable alternative to plastic.
Aside from its eco-friendly attributes, PLA is also a great option for paper cups. However, it is not yet available on the market as a lid for paper coffee cups.
PE is a plastic that is mostly used in food packaging. Its main application is to coat paper cups to make them waterproof. Although it is not a green material, it is strong and cheap.
In comparison, PLA is a relatively new player in the food packaging arena. Initially, it was only used to coat plastic glasses for cold drinks. Now, it is used to coat various types of paper.
There are many different kinds of PE and PLA coated paper. While some companies still use PE to coat their paper products, others are starting to use the more efficient and sustainable PLA.
Aside from its impressive water resistance, PLA is also a viable biodegradable alternative to PE. While the process may take a little longer to achieve biodegradability, it is still possible. To be sure, the lining of paper cups with PLA is not the easiest thing to compost.
Composting PLA coated paper
It has been a challenge for the coating paperboard industry to find an efficient solution to the problem of paper recycling. Fortunately, new technology has enabled the use of PLA coated paperboard to reduce the number of paper products that end up in landfills.
Plastic coatings, such as PLA, are biodegradable polymers made from renewable resources. They provide strength and stability to paper packaging.
Some of the more common plastic coated paper products are milk cartons, juice cartons, take-out containers, frozen food containers, and hot paper drinking cups. However, most of these applications have traditionally been disposed of by incineration or land filling.
One option is to recycle the PLA-coated paperboard in a facility certified for composting. This gives retailers, waste management companies, and brand owners an additional tool to market the eco-friendly qualities of their products.
Until recently, the main drawback to using PLA-coated paper was that it was not completely biodegradable. While the film could break down in a natural environment, it would take over a decade for the paper to decompose.
Luckily, the latest developments in PLA coated paper have created a better alternative to plastic cups. The latest cups are manufactured from recyclable materials, and they are temperature treated to ensure that they will be completely decomposable.
To make a paper bowl, you need to apply a coated PLA paper in sheet. When the paper is heated, the PLA film is pressed against it to form a waterproof layer.
