Stamping on film and plastic is a process of converting a flat surface into a molded one, giving depth to some areas of the surface in relation to other parts. This is done with a set of combined steel rolls, joined together to record the pattern from top to bottom and closed under high pressure. Alternatively, it can be done with a single roll of carbon steel engraved against a composite support roll. The materials that can be stamped are quite varied, including glass, textile fabric, non-woven fabrics, sheet metal, paper, plastic films and leather.
The embossing process is used to create a variety of effects on plastic films, such as adding texture, creating patterns or logos, or even creating a 3D effect. The embossing process is relatively simple and can be done with either hot or cold embossing. Hot embossing involves heating the plastic film until it is malleable and then pressing it against a die or mold. This method is often used for intricate designs or patterns that require more detail.
Cold embossing does not require heat and instead uses pressure to press the plastic film against the die or mold. This method is often used for simpler designs or logos. The type of embossing that can be done on plastic films depends on the type of plastic being used. For example, polyethylene terephthalate (PET) films are often used for food packaging and are suitable for both hot and cold embossing. Polypropylene (PP) films are often used for medical packaging and are suitable for cold embossing only.
Embossing plastic films can be an effective way to add texture, patterns or logos to your product packaging. It is important to consider the type of plastic being used and whether hot or cold embossing is required before beginning the process.
