Film thickness
Film thickness in packaging films refers to the thickness of the film, which is typically measured in micrometers (µm or mµ). Film thickness is an important parameter for packaging films. The thickness of a film has various effects on the packaging process and directly influences the mechanical properties of the packaging, including its strength, tear resistance, puncture resistance, and flexibility. Thicker films tend to have greater strength and resistance to external factors such as damage during transport or handling.
Barrier properties—that is, the ability to block gases, moisture, and other substances that could affect the shelf life and quality of the packaged products—can also be related to the strength of a film.
The ability to be processed in packaging machines and to ensure a reliable seal is also related to the strength of the film.
Density
Closely related to film thickness is density, another key parameter. In the field of packaging films, the term “density” refers to the amount of material present in a given volume of film. This value is a measure of mass per unit volume and is typically expressed in grams per cubic centimeter (g/cm³) or kilograms per cubic meter (kg/m³).
The film density affects various aspects of the film:
- Mechanical Properties: Density can affect the film’s strength, stiffness, and elongation properties. Generally, films with higher density have greater strength and stiffness, while films with lower density may be more flexible and stretchable.
- Barrier Properties: Film density also affects barrier properties, particularly the ability to block gases such as oxygen and water vapor. Generally, films with higher density offer better barrier performance against gases and moisture.
- Material Consumption: Film density affects material consumption during production. films With higher density, films contain more material per unit volume and therefore require more raw material for their production. This can increase production costs but can also result in a film with improved properties. In the ongoing development of new environmentally friendly films , producing films that are as thin as possible while remaining durable films is a key consideration.
- Cost-effectiveness: films with an appropriate density that provides the necessary properties for the packaging application can be a more cost-effective choice, as they offer the desired performance characteristics at an acceptable cost-benefit ratio.
Sustainability and Resource Conservation
The ongoing development of films that are as thin as possible while maintaining high tear strength, durability, and processability is a key focus in the packaging industry. Today, we offer high-techfilms with reduced thickness while providing optimal processing conditions and high tear strength.
The development of thin films with improved properties can save material; this leads, on the one hand, to lower material costs and, on the other hand, to a reduction in the use of raw materials.
Optimal packaging results even with thinner film gauges
With our state-of-the-art manufacturing processes and materials, we offer films in all thicknesses and for every application. When it comes to using thinner films , we ensure optimal processing capabilities with a wide range of packaging machines . As a system manufacturer with over 30 years of experience, we offer a wide range of packaging machines to meet every need and requirement.
Reliable sealing without compromising on quality goes without saying. Overall, film thickness therefore plays a crucial role in the use of packaging films.
