OPS, or oriented polystyrene, is a cheaper plastic that can be formed into food packaging. However, OPS is a risky investment for companies because it is a firm plastic that is prone to cracking and shattering, which poses safety concerns. OPS is also difficult to recycle, as it is harder to break down and reconstruct. For these reasons, many companies are making the switch to PET packaging, which is more easily recycled and has superior transparency.

What You'll Learn
OPS is a cheaper alternative to APET
OPS, or oriented polystyrene, is a cheaper alternative to APET, or amorphous polyethylene terephthalate. While OPS is a low-priced material, it has limited applications due to its brittleness and lack of durability. OPS is prone to cracking and shattering, which not only poses safety risks but also impacts the shelf life of food products by allowing oxygen to enter and cause spoilage.
On the other hand, APET is a more versatile, durable, and cut-resistant material. It offers heightened transparency, making it ideal for food packaging and containers. APET's structural integrity helps prolong the lifespan of food items by acting as a defence against oxygen and temperature changes.
Despite OPS's affordability, its limitations in terms of versatility and fragility make it a less favourable option for food packaging. APET's superior strength, clarity, and resistance to impact damage make it a more reliable and sustainable choice, despite its higher price point.
Furthermore, APET is widely accepted by recycling programs, whereas OPS is often rejected due to the difficulty in breaking it down and reconstructing it. This recyclability factor also contributes to APET's overall sustainability and cost-effectiveness, as recycled content can be incorporated into new APET containers.
While OPS may be a cheaper initial investment, APET's durability, functionality, and recyclability make it a more cost-effective and environmentally friendly option in the long run.

OPS is a firm plastic prone to cracking
OPS, or oriented polystyrene, is a type of plastic that can be formed into packaging. It is a cheaper option than other plastics, such as APET (amorphous polyethylene terephthalate). However, OPS has limitations when it comes to food preservation. It is a firm plastic that is prone to cracking, which can be a safety hazard as it can cause scratches and cuts. OPS tends to have sharp edges when cracked, making it unsuitable for drinking cups.
OPS is not widely accepted by recycling firms due to the difficulty in breaking it down and reconstructing it. Its brittle nature also makes it more likely to shatter, and oxygen can easily penetrate a container made from OPS, leading to food spoilage. This limits its versatility in storing food items, especially at cooler temperatures.
In contrast, APET is a more durable and cut-resistant material that offers superior clarity and transparency. It prolongs the shelf life of food items by acting as a defence against oxygen, and it can withstand temperatures as low as -20°F, making it suitable for refrigerators and freezers. APET is also safe, sustainable, and worth the investment for food presentation and preservation.
While OPS has advantages in terms of cost and efficiency during production, its limitations in food preservation and recyclability make it less desirable than alternative materials like APET. OPS's tendency to crack and shatter underscores its fragility and potential safety concerns, reinforcing the preference for other options in the market.

OPS is not widely accepted by recycling firms
OPS, or oriented polystyrene, is a cheaper plastic that can be formed into food packaging. However, OPS is not widely accepted by recycling firms. This is because OPS is difficult to break down and reconstruct. OPS is also a firm plastic that is prone to cracking, which can cause safety issues. The brittle substrate can lead to scratches and cuts, and it leaves behind sharp edges when cracked. As a result, OPS is not recommended for use in drinking cups or other applications where it may come into direct contact with consumers.
OPS has limited versatility when it comes to preserving food items at room temperature or in cooler settings. It is very brittle and more likely to shatter, allowing oxygen to seep into the container and cause food spoilage. This makes OPS less suitable for food packaging compared to other plastics like PET, which has higher structural integrity and can prolong the lifespan of food items.
PET (polyethylene terephthalate) is a more commonly used plastic in food packaging that is fully recyclable and can be turned into a multitude of new products. It is tough, flexible, and has high impact strength, making it ideal for packaging fresh produce, snacks, and drinks. PET is also lightweight, shatterproof, and compliant with food hygiene and safety standards, making it a preferred choice for retailers and consumers alike.
While OPS may be more cost-effective and efficient to produce due to its lower molding time and temperature, its limitations in terms of recyclability and durability make it less desirable from an environmental and safety perspective. As a result, recycling firms tend to favor other types of plastics that are easier to process and less likely to pose safety hazards.
Overall, OPS's lack of widespread acceptance by recycling firms can be attributed to its difficult recyclability, safety concerns, and the availability of more versatile and sustainable alternatives. To promote sustainability and reduce waste, it is essential to consider the recyclability of different plastics and choose materials that are widely accepted by recycling programs.

OPS is used for bakery food items
Oriented polystyrene (OPS) is a cheaper plastic option for food packaging. It is a firm plastic that is produced by stretching the extruded polystyrene foil, which makes the material stronger and improves visibility through the material. OPS is suitable for packaging dry and primarily cold foods, such as bakery, deli, and freezer applications, that will not be heated up in the packaging. OPS is also used for bakery food items.
OPS is not a widely recycled plastic. Most recycling firms do not accept OPS because it is difficult to break down and reconstruct. It is also not recommended for drinking cups because it is brittle and prone to cracking, which can cause scratches and cuts. OPS leaves behind sharp edges when cracked.
However, OPS can be recycled into new raw material for non-food purposes. It is important to check with your local recycling facility to see if they accept OPS for recycling. As a general rule, the smaller the recycling code number, the more common it is for the plastic to be recycled and accepted by local facilities.
While OPS is a cheaper option for food packaging, there are alternative substrates that offer better transparency, durability, and cut resistance, such as APET (amorphous polyethylene terephthalate). APET is a more sustainable option that is widely accepted by recycling programs and offers superior clarity, even with lids.

OPS is not versatile for preserving food items
OPS, or oriented polystyrene, is a cheaper plastic substrate that can be formed into food packaging. However, OPS has limited versatility when it comes to preserving food items. Its major drawbacks are its brittle nature and lack of durability, which make it prone to cracking and shattering. This not only poses safety risks, as it can cause scratches and cuts, but also compromises the integrity of the packaging, leading to food spoilage.
OPS is more difficult to recycle than other plastics due to its rigid structure, making it challenging to break down and reconstruct. This lack of recyclability is a significant disadvantage in an era where sustainability is a key concern for both consumers and businesses.
In contrast, APET (amorphous polyethylene terephthalate) is a superior alternative for food packaging. It offers heightened transparency, making it ideal for displaying food items and providing a clear view of the contents. APET also boasts superior structural integrity, protecting food items from oxygen and prolonging their shelf life. This feature is especially advantageous for perishable food products that require extended storage or transportation.
Additionally, APET is durable, cut-resistant, and safe to handle. Its ability to withstand temperatures as low as -20°F (-28.8°C) makes it suitable for refrigerator or freezer storage. APET's versatility and sustainability align with the growing demand for eco-friendly packaging solutions, as evidenced by legislation like California's ban on polystyrene foam food containers.
While OPS may have its place in specific applications, its limitations in preserving food items and its environmental impact make it less desirable compared to more versatile and sustainable alternatives like APET.
