Questions about cardboard cores and tubes are often asked, so we created this cardboard tube and core FAQ blog post just for you. Cardboard Cores – Cardboard cores and tubes are an important part of our daily lives. Although we may not be familiar with this fancy name, we use them every day. Everything from cellophane tape to toilet paper consists of a cardboard core. These cores are very practical and save our time and energy, thus making our lives more stress-free and manageable.
1. How are cardboard tubes made?
The production methods and machinery of spiral tubes and spiral tubes are very different. We produce both types. Spiral cardboard tubes are made by applying an adhesive to the top side of a cardboard strip (also called a web or ply) and then using rubber wrap to continuously wrap the cardboard around a steel mandrel, pulling the cardboard to the mandrel. superior. The pipe is then cut to the desired length using a flying knife while continuously winding the pipe.
Convoluted cardboard tubes are made using a single sheet of cardboard. Typically, the sheet is unwound from a large spool and cut to the desired length on a machine. The width of the sheet is determined by the width of the large reel. The adhesive is then applied to one side of the sheet before the “edge” of the sheet is fed into the grooved mandrel. The mandrel is then rotated and the plate is wrapped around the mandrel to form a tube. The tube then falls off the mandrel and the machine is ready to start the next cycle.
1) What is the difference between a spiral tube and a gyrotron?
The manufacturing processes of spiral cardboard tubes and convoluted cardboard tubes are completely different. They also differ greatly visually; spiral tubes often have an easily identifiable spiral mark on the outside, where the outer band spirals next to itself (“butt”), or an overlapping paper “cover” on the outside ( thin layer). Generally speaking, the manufacturing tolerances of spiral tubes are tighter and the finish is higher than that of spiral tubes.
Convoluted cardboard tubes are made from a single sheet of paper and have straight seams that run along the length of the tube. If this seam is ground into a feathered edge, it’s not always easy to spot. Because they are made from a single piece of material, the geometric range of gyrotrons is more restricted than that of spiral tubes.
However, the monolithic manufacture of spiral tubes gives them two distinct advantages: first, they can withstand higher internal pressures (important for pyrotechnic purposes), and second, they have higher beam strength (compared to equivalent Compared to spiral tubes), this means they can be a cheaper option for many textile and materials processing applications where beam intensity is an important part of the specification.
2. What is a cardboard core?
Paper cores are sturdy cardboard cylinders used to package items. Most are made from pulp fibers; however, plastic and metal cores are also available on the market. They are used as a sturdy base around which material is wrapped for storage and distribution.
There are a variety of cores on the market, including industrial cores, textile cores, tape cores, flexible film cores, label cores, and more. The options available are almost endless. They vary widely in length, wall thickness, inner and outer diameters. Depending on the intended use, manufacturers can produce paper core tubes from heavy-duty thick cardboard or less durable paper or thinner cardboard.
Cardboard cores are a boon for entrepreneurs. Many business people are afraid of sending products to customers via mail. Because a product may be intact when packaged, but may be damaged by pushing, pulling, stacking, and rough handling during transportation and warehouse storage. The end consumer will receive a damaged product as a result. It can create the wrong impression about your brand, which can impact your business. Additionally, even in brick-and-mortar stores, storing items for extended periods of time is a nightmare for many because over time, items can become damaged or wear out, and wear and tear can cause collateral damage.
Thanks to the cardboard cores, they stopped all of this from happening. They provide the required stability and ensure your products are stored and transported safely. Suppose you want to know how? We’ve got you covered. In this article, you will learn the basics of cardboard cores, their manufacturing process, and their uses.
1) How are cardboard cores made?
You can broadly divide cardboard cores into two types: spiral cores and convoluted cores. The two cores have different manufacturing processes.
First, the raw materials are set up to be fed into the machine. The paper used is generally 4 inches wide. Depending on the number of layers, the thickness of the core will vary. The paper roll is set at an angle to ensure a seamless spiral. Then thread the strip of paper through the pan of glue. They are then wound around a mandrel at an angle. The inner diameter of the core depends on the size of the mandrel. Finally, as the core comes out of the mandrel, the blade moves at the same speed as the core, cutting it to the desired size.
Convolute tubes are made by rolling up square-sized paper with the edges of the paper parallel to the axis of the tube. Wound pipe is of higher quality than spiral wound pipe, but the price is also higher. They are used in a wide range of industrial applications including textiles, metal foils, and even high-pressure applications such as rockets, fountains, candles, etc.
3. What is the difference between a cardboard tube and a cardboard core?
Cardboard/ Paper Tubes are used for packaging items where the product goes inside the tube and remains there to protect it from external damage, heat, and moisture. There are many ways to use it. Therefore, they are also called mail tubes or postal tubes. Industrial tubes, on the other hand, are heavy-duty cardboard tubes used for heavier jobs like construction.
Instead, cardboard cores are cylindrical components used to carefully wrap material around them to give an item internal strength and keep it intact.
1) What is the use of cardboard tube core?
- Since the cardboard tube and core are made from 100 parts recycled paper, they are environmentally friendly and reduce your carbon footprint.
- Tape, paper, aluminum foil, plastic foil, stretch film, wire, fabric, cellophane tape, disposable paper products, dental floss cores, foam, thermal transfer ribbons, stickers, and many other products require cardboard cores.
- In addition to general use, you can also use industrial cardboard cores for construction purposes. You can use it as a structural support for concrete columns and similar structures.
- After serving their purpose, they can also be used in DIY projects to decorate your space.
- Customize paper tubes to meet your needs and promote your business. Especially in supermarkets, beautifully packaged and beautifully printed products will attract attention and stimulate consumers to buy.
- You can print and color the inside and surface of the cardboard tube to suit your marketing needs.
- In addition to reducing scrap, it also minimizes waste in the final product.
- Carry out proper research before choosing a core and tube manufacturer you can trust so you can have peace of mind. Your delivery time can be reduced.
- You can get high-quality cardboard cores made from 100 recycled fiberboard in 100-diameter tubes from leading manufacturers like Tube Wrapping.
- Cardboard cores are recyclable. Moreover, they are odorless, non-toxic, safe, and hygienic.
- Considering its reusability, you won’t have to spend money on it again and again.
- Since the raw materials used are only paper and glue, the cost is lower, so you don’t have to spend a considerable portion of your money on packaging needs.
- Cardboard cores are lightweight and therefore inexpensive to ship. It reduces shipping costs.
- Although the core made of cardboard was durable, it was old and rusty.
- A magnetic core with a polished surface helps spin the disc inside it without damaging or damaging the material.
4. FAQ
Here are some frequently asked questions about cardboard tubes and cardboard cores.
1) Are the cardboard core and tube waterproof?
No, because cardboard inherently absorbs water. However, there is a wax-dip process that provides some degree of water resistance. This is useful for pyrotechnic applications or where extended tube life is required.
2) Can cardboard tubes and cores be recycled?
Yes, that’s right. Cardboard tubes and cores are considered one of the most environmentally friendly types of packaging because they are made from renewable resources. Cardboard is one of the materials with the lowest environmental impact. It’s 100% recyclable and 100% biodegradable.
3) What happens to the cardboard core after recycling?
Cardboard is collected by waste merchants or original manufacturers and returned to cardboard mills, where it is graded for quality, screened for contaminants, and repulped (shredded and mixed with water). It is then fed back into the papermaking process.
4) How are cardboard cores used in different industries?
Many industries and processes use cardboard cores. Nearly every type of tube or core is likely to be used in some industrial application, from textiles and carpets to tapes, labels, and films. And each one is different. For example, the core material of wrappers and packages does not need to be as durable or strong as the heavy-duty core materials used in the flooring industry.
Gyrotrons or spiral tubes used in pyrotechnics must be manufactured to be safe and reliable. When it comes to flexible films, we know it’s important to manufacture them with the right level of compressive strength.
