Due to its uncoated characteristics and coarse fibers, common issues include dust and paper fibers during printing, excessive paper stiffness causing machinery damage, poor print quality due to low surface smoothness, susceptibility to deformation when wet, and fading and brittleness under light. Insufficient interlayer bonding strength can also easily lead to delamination in kraft paper with high basis weight. Common problems in production and processing:<\/span><\/li>\n<li><span style=\"font-size: 14pt;\">Dust and paper fibers (Surface dust): Kraft paper has a porous and loose surface, making it prone to dust during printing, which seriously affects print quality. Paper with better surface smoothness should be selected.<\/span><\/li>\n<li><span style=\"font-size: 14pt;\">Paper stiffness and machinery damage: Due to its long-fiber characteristics, high-basis-weight kraft paper has extremely high stiffness, which can cause mechanical damage to printing machines.<\/span><\/li>\n<li><span style=\"font-size: 14pt;\">Difficulty in color development: Because kraft paper is brown, if the design colors are too light or high saturation is required, they are easily affected by the background color, making color reproduction difficult.<\/span><\/li>\n<li><span style=\"font-size: 14pt;\">Rough surface (Excessive ink absorption): Uncoated kraft paper is relatively rough and highly absorbent, easily causing &#8220;ink penetration&#8221; or unclear printing. Pretreatment is often required before printing.<\/span><\/li>\n<li><span style=\"font-size: 14pt;\">Insufficient interlayer bonding strength (Delamination): High-basis-weight kraft liner paper may delaminate between the surface layer and core layer if production controls are not properly managed.<\/span><\/li>\n<li><span style=\"font-size: 14pt;\">Deformation and brittleness during storage: Kraft paper is sensitive to moisture. Improper storage (high temperature or excessively dry conditions) can cause moisture to evaporate or be absorbed, resulting in paper deformation and brittleness.<\/span><\/li>\n<li><span style=\"font-size: 14pt;\">Light-induced fading: Kraft paper contains lignin; prolonged exposure can cause fading and yellowing, affecting the appearance of the paper.<\/span><\/li>\n<\/ol>\n<table style=\"border-collapse: collapse; width: 100%;\">\n<tbody>\n<tr>\n<td style=\"width: 100%;\"><span style=\"font-size: 14pt;\"><img loading=\"lazy\" decoding=\"async\" class=\"alignnone size-full wp-image-5299\" src=\"https:\/\/hadupack.com\/wp-content\/uploads\/2023\/07\/giay-kraft-2-2.jpg\" alt=\"\" width=\"2000\" height=\"1000\" srcset=\"https:\/\/hadupack.com\/wp-content\/uploads\/2023\/07\/giay-kraft-2-2.jpg 2000w, https:\/\/hadupack.com\/wp-content\/uploads\/2023\/07\/giay-kraft-2-2-768x384.jpg 768w, https:\/\/hadupack.com\/wp-content\/uploads\/2023\/07\/giay-kraft-2-2-1536x768.jpg 1536w, https:\/\/hadupack.com\/wp-content\/uploads\/2023\/07\/giay-kraft-2-2-300x150.jpg 300w\" sizes=\"auto, (max-width: 767px) 89vw, (max-width: 1000px) 54vw, (max-width: 1071px) 543px, 580px\" \/><\/span><\/td>\n<\/tr>\n<\/tbody>\n<\/table>\n<p><span style=\"color: #0000ff; font-size: 14pt;\"><em><strong>Proposed solutions:<\/strong><\/em><\/span><\/p>\n<ol>\n<li><span style=\"font-size: 14pt;\">Adjust printing techniques: A &#8220;clear varnish coating&#8221; can be applied before printing to smooth the paper surface and optimize effectiveness.<\/span><\/li>\n<li><span style=\"font-size: 14pt;\">Improve storage conditions: The paper should be stored in an environment with controlled temperature and humidity, avoiding direct sunlight.<\/span><\/li>\n<li><span style=\"font-size: 14pt;\">Pay attention to temperature and humidity: When printing on high-basis-weight kraft paper, appropriate &#8220;moisture conditioning&#8221; can reduce stiffness and protect the printer.<\/span><\/li>\n<\/ol>\n<table style=\"border-collapse: collapse; width: 100%;\">\n<tbody>\n<tr>\n<td style=\"width: 100%;\"><span style=\"font-size: 14pt;\"><img loading=\"lazy\" decoding=\"async\" class=\"alignnone size-full wp-image-5305\" src=\"https:\/\/hadupack.com\/wp-content\/uploads\/2023\/07\/giay-kraft-7.jpg\" alt=\"\" width=\"800\" height=\"800\" srcset=\"https:\/\/hadupack.com\/wp-content\/uploads\/2023\/07\/giay-kraft-7.jpg 800w, https:\/\/hadupack.com\/wp-content\/uploads\/2023\/07\/giay-kraft-7-768x768.jpg 768w, https:\/\/hadupack.com\/wp-content\/uploads\/2023\/07\/giay-kraft-7-100x100.jpg 100w, https:\/\/hadupack.com\/wp-content\/uploads\/2023\/07\/giay-kraft-7-300x300.jpg 300w, https:\/\/hadupack.com\/wp-content\/uploads\/2023\/07\/giay-kraft-7-150x150.jpg 150w\" sizes=\"auto, (max-width: 767px) 89vw, (max-width: 1000px) 54vw, (max-width: 1071px) 543px, 580px\" \/><\/span><\/td>\n<\/tr>\n<\/tbody>\n<\/table>\n<h3><span style=\"color: #ff0000; font-size: 14pt;\"><em><strong>Why is Kraft paper better than ordinary paper<\/strong><\/em><\/span><\/h3>\n<p><span style=\"font-size: 14pt;\">First of all, kraft paper is stronger due to its low lignin content and high sulfur ratio.

In addition, Kraft paper can be folded, cut and shaped to create custom packaging or decorative elements.<\/span><\/li>\n<li><span style=\"font-size: 14pt;\">Environmental impact of Kraft paper: One of the main reasons kraft paper has become popular is its minimal environmental impact. As a biodegradable and recyclable material, kraft paper provides a sustainable alternative to traditional packaging materials. By choosing kraft paper, businesses and consumers can reduce their carbon footprint and contribute to a more environmentally friendly approach to packaging and crafts.<\/span><\/li>\n<\/ol>\n<table style=\"border-collapse: collapse; width: 100%;\">\n<tbody>\n<tr>\n<td style=\"width: 100%;\"><span style=\"font-size: 14pt;\"><img loading=\"lazy\" decoding=\"async\" class=\"alignnone size-full wp-image-5301\" src=\"https:\/\/hadupack.com\/wp-content\/uploads\/2023\/07\/giay-kraft-4-1.jpg\" alt=\"\" width=\"940\" height=\"454\" srcset=\"https:\/\/hadupack.com\/wp-content\/uploads\/2023\/07\/giay-kraft-4-1.jpg 940w, https:\/\/hadupack.com\/wp-content\/uploads\/2023\/07\/giay-kraft-4-1-768x371.jpg 768w, https:\/\/hadupack.com\/wp-content\/uploads\/2023\/07\/giay-kraft-4-1-300x145.jpg 300w\" sizes=\"auto, (max-width: 767px) 89vw, (max-width: 1000px) 54vw, (max-width: 1071px) 543px, 580px\" \/><\/span><\/td>\n<\/tr>\n<\/tbody>\n<\/table>\n<h2><span style=\"color: #008000; font-size: 14pt;\"><em><strong>What is PE-coated kraft paper?<\/strong><\/em><\/span><\/h2>\n<p><span style=\"font-size: 14pt;\">PE-coated kraft paper is a composite packaging material created by coating the surface of kraft paper with a polyethylene (PE) plastic film using extrusion technology.
