How Unique Custom Labels are Made with Cold and Hot Foil Technologies

Today, there are a wide variety of printing technologies available to manufacturers to create incredibly unique and beautiful custom labels.  Two of those technologies include cold foil and hot foil label applications.

This post is meant to help you understand how cold and hot foil labels are made, how each may be useful to sell your products and the major differences between them.

Cold Foil Labels

Cold foil labels are made by applying foil (typically aluminum) onto a substrate (usually paper or film) through a cold stamping process. In this process, the foil is transferred onto the substrate with adhesives by applying pressure, without the use of heat or solvents. The substrate is first printed with a UV curable adhesive and then the foil is applied on top using a die and a high-pressure press. The pressure from the press forces the foil to adhere to the adhesive on the substrate, creating a brilliant, eye-catching and reflective finish.

Cold foil labels are highly useful for a number of reasons. Some of these include:

  1. Aesthetic appeal: Cold foil labels offer a shiny and metallic appearance that can make a product stand out on store shelves and draw the attention of customers.
  2. Durability: The foil is resistant to scratches, fading, and tearing, making it an ideal choice for labeling products that are subject to rough handling or exposure to the elements.
  3. Versatility: Cold foil labels can be printed in a wide range of colors, allowing manufacturers to create customized labels that match the colors of their products.
  4. Cost-effectiveness: Cold foil labels are relatively inexpensive to produce, making them a cost-effective labeling solution for manufacturers.
  5. Security: Cold foil labels can be used to create holographic or tamper-evident effects, making them ideal for labeling high-value products or for use in applications where security is a concern.

In summary, cold foil labels offer a combination of aesthetics, durability, versatility, cost-effectiveness, and security, making them an ideal choice for a wide range of labeling applications.

Hot Foil Labels

Hot foil labels (or stamping) are a type of labeling technology that uses heat and pressure to transfer metallic foil onto the surface of a label. The process involves the use of a hot foil stamping machine, which heats a metal plate and presses it onto the label material, leaving a shiny, metallic finish.

These labels are often used in a variety of applications, including product labeling, branding and promotional materials, packaging, and stationery. The following are some of the key benefits of hot foil labels:

  1. Durability: The metallic finish of hot foil labels is resistant to wear and tear, making them suitable for use on products that are exposed to the elements or handled frequently.
  2. Eye-catching appearance: The shiny metallic finish of hot foil labels makes them highly noticeable, making them ideal for use on products that need to stand out on the shelf.
  3. Versatility: Hot foil labels can be made in a range of colors and finishes, including gold, silver, copper, and colored foils, allowing for a wide range of design options.
  4. Customizability: Hot foil labels can be produced in a range of sizes and shapes, and can be printed with custom logos, text, and graphics, making them ideal for use in branding and promotional materials.
  5. Cost-effectiveness: Compared to other labeling technologies, such as embossing or debossing, hot foil labeling is relatively cost-effective, making it an attractive option for businesses looking to create high-quality, eye-catching labels on a budget.

 Cold Foil vs. Hot Foil Labels

Cold foil labels and hot foil labels are two methods used for adding a metallic finish to print labels or packaging. While both methods produce similar results, there are some key differences between them:

Cold Foil Labels:

  • Cold foil labels use a pressure-sensitive adhesive and a die-cutting process to apply a thin metal layer to the label or packaging.
  • The metal layer is pre-printed on a release liner and then transferred to the label material.
  • The process does not require heat, which makes it a more cost-effective option and can be used on heat-sensitive materials such as films and plastics.
  • Cold foil has a lower metallic shine compared to hot foil, which can be a drawback for some designs.

Hot Foil Labels:

  • Hot foil labels use heat and pressure to transfer metallic foil to the label or packaging.
  • The process uses a heated die to melt the foil and transfer it to the label material.
  • Hot foil creates a more pronounced and brighter metallic finish compared to cold foil, making it ideal for high-end labels or packaging.
  • The process can be more expensive and time-consuming compared to cold foil, and may not be suitable for heat-sensitive materials.

Ultimately, the choice between cold foil and hot foil labels will depend on the specific needs of your project, including design requirements, budget, and materials.
