1. Introduction
A. Definition of biodegradable stretch film
Biodegradable Stretch Film is a type of packaging material that is designed to be both stretchable and biodegradable. It is commonly used to wrap products for transportation, storage, or display. The stretch film is typically made from a combination of natural and synthetic materials, such as cornstarch and polylactic acid (PLA), which are capable of decomposing naturally over time.
The biodegradable stretch film is produced using a similar manufacturing process to traditional plastic stretch film. The materials are mixed and heated until they become malleable, then they are stretched out and cooled to form a thin, flexible sheet. The finished product can be produced in a range of thicknesses and lengths to suit different applications.
When the biodegradable stretch film is discarded, it begins to break down naturally over time through the action of microorganisms. This is achieved through a process called biodegradation, in which the material is broken down into smaller components that can be absorbed into the natural environment without causing harm. The exact rate of biodegradation depends on a range of factors, such as the thickness of the film, the temperature and moisture levels in the environment, and the presence of microorganisms.
Overall, biodegradable stretch film is an innovative and sustainable packaging material that offers many advantages over traditional plastic packaging. As consumers become increasingly aware of the environmental impact of their purchases, biodegradable stretch film is likely to become more widely used in the future.
B. Definition of traditional stretch film
Traditional stretch film, also known as conventional stretch film, is a type of plastic packaging material commonly used for wrapping and securing products for transportation, storage, and display. It is typically made from a blend of linear low-density polyethylene (LLDPE) and other additives that give it strength, flexibility, and cling properties.
The production process of the traditional stretch film begins with the mixing of LLDPE pellets and other additives, such as tackifiers, slip agents, and UV stabilizers. The mixture is then melted and extruded into thin, flexible sheets. The sheets are then stretched longitudinally and transversely to improve their strength and flexibility. The stretching process aligns the molecules of the film, giving it the ability to stretch and conform to the shape of the product it is wrapping.
Traditional stretch film is available in a variety of widths, thicknesses, and colors to suit different applications. It is typically sold in rolls that can be easily dispensed using a handheld dispenser or machine.
The main advantage of traditional stretch film is its ability to securely wrap and protect products during transportation and storage. It provides a tight seal around the product, preventing it from shifting or moving around during handling. It also helps to protect the product from dust, moisture, and other contaminants. Additionally, traditional stretch film is highly transparent, making it easy to identify the contents of the wrapped product.
One of the downsides of traditional stretch film is its environmental impact. As it is made from non-renewable resources, it is not biodegradable and can take hundreds of years to decompose in landfills. Additionally, its production and disposal can release harmful chemicals and greenhouse gases into the environment.
In recent years, there has been a growing interest in eco-friendly alternatives to traditional stretch films, such as biodegradable and compostable stretch films made from renewable resources. These alternatives offer similar performance to traditional stretch film while reducing the environmental impact of packaging.
2. Benefits of biodegradable stretch film
