1. What is wet-strength paper? As the name implies:  wet paper  is paper that will not spread when wet. Commonly used in label packaging. Wet-strength Paper 2. Characteristics of wet paper When ordinary paper meets water, it will lose most of its original dry strength characteristics. However, the  wet-strength paper   has the characteristics of resisting decomposition and cracking when water is saturated. Paper is classified as wet strength when it maintains 15% or more of its dry tensile strength. High-quality wet-strength paper can keep up to 50% or more dry strength after being immersed in water. The characteristics of the wet paper include: 1) High gloss, strong metallic feeling, good metallization uniformity, smooth surface, and good aluminum adhesion. 2) Excellent adhesion with ink, smooth paper without curling. 3) Applicable to offset printing, gravure printing, flexographic printing, etc. 4) Excellent performance when used for labels. 5) High water absorption. 6) High alkali r

For watch enthusiasts and collectors, the question of whether to use a watch winder is a topic of ongoing debate. A watch winder is a device designed to keep automatic watches running when they are not being worn. While some argue that watch winders are essential for maintaining the accuracy and longevity of automatic watches, others question their necessity and potential drawbacks. The Pros of Using a Watch Winder : 1. Continuous Running: Watch winders keep automatic watches running continuously, ensuring that the movement stays lubricated. This can be particularly beneficial for watches with intricate complications that require continuous operation to remain accurate. 2. Convenience: For individuals with multiple automatic watches, a watch winder offers the convenience of having all watches ready to wear without the need for manual winding each time. This is especially useful for watches with complex setting procedures. 3. Preservation of Complications: Complicated watches, such as p

In an age where sustainability is paramount, the recyclability of packaging materials is a crucial consideration. Custom printed shrink film , commonly used for packaging various products, raises the question: can it be recycled? In this article, we explore the intricacies of custom printed shrink film and its recyclability, shedding light on the environmental impact and considerations for businesses and consumers. Understanding Custom Printed Shrink Film Custom printed shrink film is a versatile packaging material known for its ability to conform tightly to the shape of the product it encases when heat is applied. This property makes it ideal for packaging items of varying shapes and sizes, providing a snug and secure fit. The film is often used in industries such as food and beverage, cosmetics, and retail packaging to enhance product presentation and protection. Composition of Custom Printed Shrink Film To address the recyclability of custom printed shrink film, it's essential t

Welcome to our comprehensive guide on how long to leave a watch in a   watch winder ! As experts in the world of horology, we understand the importance of maintaining the accuracy and longevity of your cherished timepieces. In this article, we will delve into the intricacies of watch winders and provide you with valuable insights on the optimal duration for keeping your watches inside these mechanical marvels.   What is a Watch Winder? A watch winder is a device designed to mimic the natural movement of a wrist, ensuring that automatic or self-winding watches remain fully wound even when not in use. By rotating the timepiece gently, a watch winder prevents the watch's mainspring from losing tension and keeps it running smoothly.   The Purpose of a Watch Winder The primary purpose of a watch winder is to preserve the accuracy and functionality of automatic watches. When a self-winding watch is not worn regularly, it gradually loses its power reserve and may stop running altogether.
