Soft plastics are a common packaging material that is lightweight, durable, and cost-effective to manufacture and transport. It is often used for food packaging, such as bread bags, grocery bags, and plastic wrappers, as well as in ice packs and carton insulation. Soft plastics usually consist of Low-density Polyethene (LDPE), High-density Polyethene (HDPE), or Polypropylene (PP). While soft plastics can be recycled and reused, they require special recycling procedures and cannot be disposed of in regular household recycling bins. Proper identification and recycling of soft plastics are crucial to minimize their environmental impact and promote sustainability.

Soft plastics are made from Low-density Polyethene (LDPE), High-density Polyethene (HDPE) or Polypropylene (PP)
Soft plastics are a common part of everyday life for consumers and businesses. They are used in ice packs, carton insulation, bread bags, grocery bags, bubble wrap, plastic wrappers, and more. However, soft plastics can be unsustainable and harmful to the environment if they are not recycled correctly. Therefore, it is important to understand what soft plastics are, where they are used, and how to dispose of them properly.
Soft plastics usually consist of one of three types of plastics: Low-density Polyethene (LDPE), High-density Polyethene (HDPE), or Polypropylene (PP). LDPE is very flexible and ductile but has low tensile strength. It is often used for plastic bags, computer hardware packaging, toys, and casing. LDPE bottles are suitable for less corrosive fluids, such as lubricants, coolants, and some cleaning agents. Its flexibility makes it easier to squeeze, which is advantageous in manual dispensing applications. LDPE is also used in combination with HDPE in the manufacture of various consumer items such as toys, chemical plant components, electrical fittings, seals, and bushings.
HDPE, on the other hand, is known for its strength and rigidity, making it ideal for heavy-duty applications. It is commonly used for thin-gauge carrier bags, fresh produce bags, bottles, and caps. HDPE bottles are 100% recyclable, and the material can be reused over and over again. They are lightweight, adaptable, safe, and provide marketing opportunities. HDPE milk bottles are one of the most widely recycled items of packaging in the UK, with around 79% of bottles being recycled.
Polypropylene (PP) offers a balance of chemical resistance, durability, and affordability. It is a traditional plastic with a range of flexibilities and properties, and it is the most rigid type of Polyethylene. PP is considered recyclable but is not as widely accepted as HDPE.
To identify a soft plastic product, you can perform the scrunch test. If the plastic product scrunches up and doesn't bounce back, it is likely a soft plastic. It is important to separate soft plastics from normal recycling or rubbish. When recycled properly, soft plastics can be reused and blended with other components to create new products, reducing waste and the need for raw materials.

Soft plastics can be harmful to the environment if not recycled properly
Soft plastics are a type of plastic that can be easily scrunched up and doesn't bounce back. They are commonly used in bread bags, grocery bags, bubble wrap, plastic wrappers for food items, and ice packs. While soft plastics have become an everyday part of life for consumers and businesses, they can be harmful to the environment if not recycled properly.
Soft plastics, like all plastics, can have negative environmental impacts if they are not disposed of or recycled correctly. For instance, soft plastics can cause costly damage to normal plastic recycling factories and add to already overflowing landfills. Due to their lightweight nature, they can be blown out of landfills and pollute the environment. As they break down, they can enter waterways and soil, and can be ingested by animals. Additionally, the manufacturing process of soft plastics produces large amounts of carbon dioxide, contributing to high greenhouse gas levels.
It is important to separate soft plastics from normal recycling or rubbish. When recycled through proper methods, soft plastics can be reused and blended with other components to create new products, reducing the need for raw materials and energy. However, soft plastics cannot be processed at local Material Recovery Facilities (MRFs) due to mechanical issues they cause for the machinery. Therefore, they must be kept separate and, in some countries, may require specialist recycling.
To recycle soft plastics, ensure they are clean and free from food remnants. Once dry, they can be gathered and dropped off at designated soft plastics recycling bins, often found in supermarkets. By properly disposing of and recycling soft plastics, we can minimise their impact on the environment and move towards more sustainable practices.

Soft plastics are recycled separately from hard plastics
Soft plastics are typically made from Low-Density Polyethene (LDPE), High-Density Polyethene (HDPE), or Polypropylene (PP). They are characterised by their flexibility and ability to be scrunched up without bouncing back. Common examples include plastic bags, wrappers, bubble wrap, and film. Due to their widespread use, it is essential to understand how to dispose of soft plastics properly to minimise their environmental impact.
Soft plastics cannot be recycled with hard plastics and must be separated. Hard plastics, such as water or milk bottles, are considered more valuable and can be processed into recycled products at local Material Recovery Facilities (MRFs). On the other hand, soft plastics cannot be handled by MRFs because they create mechanical issues for the machinery. As a result, soft plastics are often directed to general waste.
The distinction between soft and hard plastics can be made through the "scrunch test". If a plastic item can be scrunched into a ball and stays scrunched, it is a soft plastic. Soft plastics often require specialist recycling facilities, and there may be specific drop-off points for their collection. However, it is important to note that soft plastics can contaminate other recyclable materials if not separated, making the recycling process more challenging and expensive.
Additionally, soft plastics can be more difficult to clean, especially when contaminated with food waste. This poses challenges for recycling at the source and recycling centres. While soft plastics can be recycled and upcycled into new products, it is crucial to separate and clean them properly to enable proper recycling and reduce their environmental impact.
In summary, soft plastics are recycled separately from hard plastics due to differences in their physical properties and the specialised facilities required for their processing. Proper separation and recycling of soft plastics are essential to prevent environmental harm and promote sustainability.

Soft plastics scrunch up and don't bounce back
Soft plastics are plastic materials that consist of Low-density Polyethene (LDPE), High-density Polyethene (HDPE), or Polypropylene (PP). They are characterised by their 'soft' structure, which can be easily identified by their ability to be scrunched up without bouncing back. Common examples include bread bags, grocery bags, bubble wrap, and plastic wrappers for food items. Due to their widespread use, it is essential to understand how to properly dispose of soft plastics to minimise their environmental impact.
Soft plastics have become an integral part of daily life for consumers and businesses, but they have also received negative attention due to their potential environmental harm if not recycled correctly. When improperly disposed of, soft plastics can cause damage to normal plastic recycling machinery, add to landfill waste, and pollute the environment as lightweight pieces that can be blown out of landfills. Therefore, it is crucial to separate soft plastics from regular recycling or rubbish.
To recycle soft plastics, they must be cleaned and dried to remove any food remnants. This ensures that the plastic film is ready for recycling and repurposing. Many countries offer specialist soft plastics recycling services, and some supermarkets provide soft plastics recycling bins. These recycled soft plastics can be upcycled or blended with other components to create new products, reducing the need for raw materials and energy consumption.
The scrunch test is a simple way to identify soft plastics. If a plastic item can be scrunched into a ball and doesn't bounce back to its original shape, it is considered a soft plastic. Examples of scrunchable soft plastics include plastic shopping bags and large sheets of plastic used for wrapping furniture. However, it's important to note that not all scrunchable plastics are recyclable, and certain combinations of plastic and other materials may not be accepted by recycling programs.
Additionally, there are tricks to fix warped soft plastics, such as those used in fishing baits. For instance, dipping warped tails into boiling water and then into cold water can help set the plastic to a desired position, making it softer and enhancing its underwater action as a bait. Soft plastics, therefore, have a range of applications and can be reused or recycled when properly managed.

Soft plastics can be reused and blended with other components to create new products
Soft plastics are an everyday part of life for consumers and businesses. They are used to make bread bags, grocery bags, bubble wrap, plastic wrappers for food items, ice packs, carton insulation, and more. Soft plastics usually consist of one of three types of plastics: Low-density Polyethene (LDPE), High-density Polyethene (HDPE), or Polypropylene (PP). They are identified by their soft structure, which can be scrunched up and doesn't bounce back.
While soft plastics have faced criticism and negative press, they can be recycled and upcycled into other useful products. However, they cannot be processed at a local Material Recovery Facility (MRF) due to mechanical issues. Instead, they must be separated from normal recycling or rubbish and placed in designated soft plastics recycling bins, commonly found in supermarkets across New Zealand. To recycle soft plastics, it is essential to ensure that the plastic film is clean and free from food remnants.
Additionally, blending different types of plastics is a common practice to improve certain characteristics. For example, blending LDPE with LLDPE can reduce extruder pressure and torque, enhance bubble stability, and improve melt strength. This blend finds applications in packaging, household goods, agriculture, electrical devices, construction, and more.
Overall, recycling soft plastics can help reduce environmental pollution, mitigate the impact of plastic waste, and create new products from 100% waste plastics. However, it is important to note that only a small fraction of waste soft plastics are currently recycled due to limitations in technology and the economic and environmental viability of chemical recycling methods.
