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

A. Environmentally friendly:

One of the primary benefits of using biodegradable stretch film is that it is more environmentally friendly than traditional plastic packaging materials. Biodegradable stretch film is made from natural materials, such as cornstarch and PLA, which can decompose naturally over time. As a result, the biodegradable stretch film does not contribute to the accumulation of plastic waste in landfills, which is a significant environmental concern.

Moreover, the production of biodegradable stretch film requires fewer resources and energy than traditional plastic packaging materials. The production of traditional plastic packaging materials often involves the use of non-renewable resources and chemicals, which can have harmful environmental impacts. Biodegradable stretch film, on the other hand, can be made from renewable resources, such as corn and sugarcane, reducing its environmental footprint.

B. Cost savings:

Biodegradable stretch film can also offer cost savings compared to traditional plastic packaging materials. While the initial cost of the biodegradable stretch film may be slightly higher, the long-term cost savings can be significant. Biodegradable stretch film is typically thinner and more stretchable than traditional plastic packaging materials, which means that less material is required to wrap the same product. This can result in lower packaging costs, as well as reduced transportation costs due to the lighter weight of the packaging.

Additionally, the use of biodegradable stretch film can also help to reduce waste disposal costs. Traditional plastic packaging materials can take hundreds of years to decompose in landfills, which can lead to significant disposal costs over time. Biodegradable stretch film, on the other hand, can decompose naturally, reducing the amount of waste that needs to be disposed of and the associated costs.

3. Disadvantages of biodegradable stretch film

A. Lower strength:

One of the main disadvantages of biodegradable stretch film is that it may have lower strength and durability compared to traditional plastic packaging materials. Biodegradable stretch film is typically made from natural materials, such as cornstarch and PLA, which may not have the same strength and resilience as traditional plastic materials. As a result, the biodegradable stretch film may be more prone to tearing and puncturing during transportation and storage, which can compromise the integrity of the packaged product.

To address this issue, manufacturers of the biodegradable stretch film are working to improve the strength and durability of their products through the use of new materials and production techniques. However, this may increase the cost of biodegradable stretch film and make it less competitive with traditional plastic packaging materials.

B. Limited availability:

Another disadvantage of biodegradable stretch film is that it may have limited availability compared to traditional plastic packaging materials. Biodegradable stretch film is a relatively new technology, and its production and distribution are still limited. As a result, it may be more challenging to source biodegradable stretch film in some regions, especially in areas with limited infrastructure for the collection and processing of biodegradable waste.

Moreover, the limited availability of biodegradable stretch film may result in higher prices compared to traditional plastic packaging materials. The higher cost may be due to the limited production capacity of biodegradable stretch film manufacturers and the higher cost of natural materials used in its production.

A. Strength:

Traditional stretch film is generally stronger and more durable than biodegradable stretch film. Traditional stretch film is typically made from petroleum-based plastics, which have high tensile strength and can stretch and recover without tearing. In contrast, biodegradable stretch film is made from natural materials, such as cornstarch and PLA, which may not have the same strength and durability as traditional plastics.

B. Cost:

The cost of biodegradable stretch film is generally higher than traditional stretch film. Biodegradable stretch film is made from natural materials, which are often more expensive than petroleum-based plastics used in traditional stretch film. Additionally, the production process for the biodegradable stretch film is more complex, which also contributes to its higher cost.

However, it is worth noting that the cost of the biodegradable stretch film may be offset by other cost savings, such as reduced waste disposal costs and lower transportation costs due to its lighter weight and thinner profile.

C. Availability:

The availability of biodegradable stretch film is more limited compared to traditional stretch film. Traditional stretch film is widely available and can be found in most retail and industrial settings. In contrast, biodegradable stretch film is a relatively new technology and is not yet as widely available as traditional stretch film.
