PP loose leaf bags are still quite common in our daily lives and are widely used items, but many people also have the problem of the loose leaf folder not being able to open, which is very troublesome. So, what are the common binding methods for PP loose leaf bags? Do you understand them? Now let's take a look.
1. Riding horse binding is one of the common binding methods, which is often used when there are few PP loose leaf bags that need to be bound. The processing price will be cheaper, the process will be simpler, and the production speed will be faster. However, when there are many loose pages, there will be obvious bulging, and the center of the plate is prone to deviation, and even the upper and lower edges of the spine are easily damaged.
2. Iron wire paperback is usually used in situations where there are many PP loose leaf bags, and the weight of book block paper is relatively low. This binding cost is relatively low, but efficiency is relatively high. But the wire is prone to moisture and corrosion, which affects the quality of binding. In addition, if the weight of the paper is too large, it can also affect the reading of books.
3. Wireless adhesive bonding is currently a commonly used method, which can be divided into hot adhesive, cold adhesive, and PUR adhesive. However, it should be noted that after the hot melt adhesive is soaked and dried, the book cannot be opened to the bottom, and the binding point will be about 3mm unclear. Therefore, an inner page version should be used, with the heart position 3mm away from the mouth.
4. Lockstitch binding is a commonly used binding method for PP loose leaf bags, which involves connecting the organized book stickers in a certain order and requiring locking during the connection process. This binding method can make reading more convenient, books more sturdy, and their lifespan can be improved. Some high-quality books use this method.
The above is my introduction to PP loose leaf bags, hoping to be helpful to you.
