Introduction: Labeling plays a crucial role in product identification and branding, and selecting the right labeling machine is essential for paper tube manufacturers and snacks food factories. When it comes to choosing between hot glue and water PVA glue for labeling paper tubes and cardboard tubes, there are important factors to consider. In this article, we will discuss the key differences between the two adhesive types and provide guidance on how to choose the appropriate labeling machine for your production needs.
Hot Glue Labeling Machine:
- Hot glue labeling machines use a specialized adhesive that melts at high temperatures to create a strong bond between the label and the tube surface. Here are some key points to consider:
- Superior Bond Strength: Hot glue offers excellent adhesion, ensuring that labels stay securely attached to the tubes throughout the production and distribution process.
- Versatility: Hot glue can be used for various tube materials, including paper and cardboard, making it a versatile option for different types of products.
- Resistance to Temperature and Moisture: Hot glue exhibits good resistance to temperature fluctuations and moisture, ensuring that labels remain intact even in challenging environmental conditions.
- Paper Tube Humidity request: The humidity of the paper tube is less than 12% to benefit the hot melt adhesive labeling machine, and the manufacturer is required to have a special drying box.
- Low Machine Cost: Hot glue labeling machine stick many sizes of tubes in a range ID28-130MM and no need to change mould.And the machine making cost is almost same with semi auto water cold glue labeling machine which stick one by one.
And this year, We also develop one new model paper can labeling machine BK-500N which only stick ID50-110mm will save 2000USD than BK-500 paper tube hot melt labeling machine.If you just want to stick manually,you can just use BK-500S to save 500USD again.
2. Water PVA Glue Labeling Machine:
Water PVA glue, also known as water-based adhesive, is a popular choice for labeling applications. Consider the following aspects:
- Easy Cleanup: Water PVA glue is water-soluble, making it easier to clean the labeling machine and remove any excess adhesive from equipment and surfaces.
- Cost-Effective: Water PVA glue is generally more affordable compared to hot glue, making it an attractive option for cost-conscious manufacturers.
- Environmentally Friendly: Water-based adhesives are considered more environmentally friendly due to their lower VOC (volatile organic compounds) content, making them suitable for eco-conscious production environments.
- Paper tube Humidity: Don’t care too much if the paper tube manufacture have dry machine or room specially.It can stick the wet paper tube directly and don’t affect the labeling result after curling.
- Machine making cost: The priciple of Water glue labeling machine is more complicated than hot melt glue.and it has to change the mould if different diameter tubes to stick in a range ID40-150mm of Semi auto cold glue label machine BKWG-CM .And if automatic water PVA glue labeling machine BKWG-C model only stick ID50-100mm.
Here Is the PVA Water Glue:
Choosing the Right Labeling Machine: To make an informed decision, consider the following factors:
- Tube Material: Evaluate the specific characteristics of your paper or cardboard tubes and ensure that the chosen adhesive is compatible with the material.
- Label Adhesion Requirements: Assess the label adhesion needs of your products. If you require a strong and long-lasting bond, hot glue may be the preferred option.
- Production Environment: Consider the temperature and humidity conditions in your production facility. Hot glue is more resilient to heat and moisture, while water PVA glue may be a suitable choice for moderate environmental conditions.
- Limited Mechanical investment budget:
- Drying room: If you have drying room in your paper tube work shop,you have conside hot melt glue labeling machine as the machine is cheap and it can be adjustable in different size fast.If you just want to dry the paper tube by air naturally,the water PVC cold glue labeling machine will be better for you.
Conclusion: Selecting the right labeling machine and adhesive type is crucial for achieving accurate and reliable labeling of paper tubes and cardboard tubes. Whether you opt for a hot glue labeling machine or a water PVA glue labeling machine, consider factors such as bond strength, tube material compatibility, production environment, and cost-effectiveness. By making an informed choice, you can enhance your production efficiency, improve the pass rate of labeled tubes, and deliver high-quality products to your customers.
