What is White Kraft paper?

White Kraft paper and Brown Kraft paper difference

There are two primary types of Kraft paper: brown Kraft paper, which is typically used for packaging, and white Kraft paper, which is mainly used for printing due to its whiteness. Some may wonder, besides appearance, what distinguishes white Kraft paper from regular brown Kraft paper. The above indicated that the colour and use are genuinely different, and their production materials are certainly not the same. Still, there are many more comparisons that can be made. In most cases, wood pulp is used to create standard brown Kraft paper. The difference between white and brown Kraft paper is that the former is created from bleached wood pulp, while the latter uses coloured wood pulp for its core and bottom layers.

Brown Kraft Paper

There are numerous benefits to using white kraft paper for food packaging; for example, it is more healthful, safer for the environment, and cheaper than other options.

To save waste, it's preferable to package food with white Kraft paper. Total wood pulp production yields white kraft paper, which can be recycled and reused indefinitely; food-grade white kraft paper is more commonly sourced from an artificial forest farm than a natural one due to the use of artificial forests and environmentally friendly reforestation practises in the former.

Expenses are reduced, saving money. For food storage, white Kraft paper is the standard. The cost of packaging will not go up due to switching to Kraft because it is more cost-effective.

Eco-friendly Recycled Kraft paper

We know that Kraft paper is eco-friendly packaging for two reasons: first, it is easily recyclable and reusable, and second, some varieties of Kraft paper are produced from the recycled waste pulp. When comparing recycled Kraft paper to standard Kraft paper, the primary distinction is the raw ingredients used. Because recycled Kraft paper employs recycled pulp, and recycled pulp often has many impurities, recycled Kraft paper is slightly poorer in physical Kraft paper quality than the original wood pulp Kraft paper. The "drop powder" phenomenon will also show up in printing some recycled Kraft papers. As a result, original wood pulp Kraft paper is typically used for market packaging with stringent performance, safety, and hygiene requirements. However, recycled Kraft papers are more commonly used for general packaging. This isn't because recycled Kraft paper is low-quality; instead, the raw materials used to make it are waste products. In terms of environmental preservation, however, recycled Kraft paper will use recycled pulp twice, considerably minimising the excessive use of forest resources, making it ideal for packaging luxury goods. Recycled Kraft paper is less expensive than traditional Kraft paper since it is made from recovered fibres.

The Weight of Kraft Paper

To get the actual weight of form, which is expressed in terms of grammes per square meter, you need only divide the length of Kraft paper by its specified width and height. However, G/SM is just a measurement technique and has nothing to do with Kraft paper's essential qualities and properties. Kraft paper of varying gramme weights likewise varies in thickness.

Suppose you don't have a micrometre, calliper, or other precision measuring device on hand. In that case, you can usually estimate the weight of a sheet of Kraft paper by rubbing it between your hands. Buy Kraft cardboard if it's appropriate for your goods without worrying too much about the thickness of documents, as the thickness of Kraft paper is proportional to its paperweight.

Suppose thin Kraft paper is used to make packaging products. In that case, the resulting lack of hardness can disrupt the printing process, reduce the printing plant's output, and even compromise the quality of the finished product. When printing, using thinner paper slows the press from 14,000 to 10,000 pages per hour, resulting in a 30% decrease in printing plant efficiency. Consequently, choosing whether to use thicker or thinner paper depends on the characteristics of the task at hand. When printing, it's essential to use high-quality Kraft paper so that the process goes as smoothly as possible and the final product lives up to the consumer's expectations.

What kind of paper is often included in a Kraft notebook? 

The cover of a typical notebook requires between 400 and 500 grammes of paper, whereas the internal page typically uses only 70 to 80 grammes. Brown Kraft paper and white Kraft paper can usually have fewer grammes used to achieve the requirements due to their superior physical qualities. If you're going with Kraft paper for the cover, you may often pick between 400 and 450 grammes. Two weights of Kraft paper are available to satisfy the demand: 50 grammes for the interior page and 70 grammes for the outside.

Brown Kraft paper, often used for the notebook's cover and back cover, is given a particular treatment to make it more durable and water resistant; the brown Kraft paper used for the notebook's inside pages, meanwhile, is smoother and lighter in colour. The qualities of Kraft paper include a soft paint that protects the eyes and a silky texture that improves the writing experience. Various types of Kraft paper are used to make notebooks, including white Kraft paper, American bull card, fine Kraft paper, writing papers, etc.

What sets apart 100% recycled Kraft paper from FSC-certified

While the raw materials employed in producing FSC-certified Kraft paper and 100% recycled Kraft paper are distinct, the end products are strikingly similar. The primary distinction between 100% recycled Kraft paper and FSC-certified Kraft paper is that the former uses original wood pulp as raw material for papermaking while the latter uses recycled pulp. As part of the Forest Stewardship Council's (FSC) Green Certification programme, each roll of FSC-certified Kraft paper can be traced back to the exact forest farm that supplied the raw materials. One can purchase FSC Kraft paper and recycled Kraft paper of the same quality from the same source. One way in which these products are similar is that they all share a commitment to preserving the environment. FSC Kraft paper, for example, is typically manufactured using artificial forest wood as raw materials, while 100% environmentally friendly recycled Kraft paper, on the other hand, makes use of recycled pulp.
