A refrigerator is more than simply a box that keeps food cold. It’s a high-tech device that employs sophisticated controls to keep humidity, light, and temperature at optimum levels for food storage.

Food wrap is essential for keeping food fresh, safe, and odourless until it’s time to eat. Mould and mildew can spread if foods aren’t stored correctly, so odours are only one aspect of the problem.

It is possible to retain nutrients and guarantee that meals do not grow stale by learning to store foods in the correct areas of the fridge using plastic food wrap.

Beyond helping to store your food, food wraps also give your food a beautiful look in the refrigerator.

For example, if you are into selling packaged goods on store shelves, Thong Guan’s Klarity plastic food wrap catches the eye of passers-by and is extremely noticeable! It’s also great for branding because it’s so transparent.


Proper Areas to Store Food in the Refrigerator

1. Top and Middle Shelves

The top and middle shelf are perfect for ready-to-eat foods like dairy products, ready meals and packaged foods, leftovers, cooked meats, and prepared salads.

To avoid infection, keep everything covered with Thong Guan Klarity plastic wrap or in sealed containers.

Ready-to-eat foods are kept on the top shelf of the refrigerator, away from raw foods, to prevent dangerous bacteria from spreading from raw to cooked meals.


2. Bottom Shelf

To prevent raw meat, poultry, and fish from contacting or leaking onto other items, place them in sealed containers or plastic wrap.

To avoid cross-contamination, raw meats should always be kept at the bottom of the fridge.

Make sure each item is wrapped or in a sealed container to avoid cross-contamination with other foods.


3. Salad and Fruit Drawer

The salad drawer is perfect for fruits, vegetables, and salads that have been washed and dried before being stored. To keep your fruit, veggies, and salad safe from contamination, wrap them in paper or plastic with air holes.

To prevent salads and herbs from drying out and to keep them fresher for longer, you can wrap them in a wet paper towel before storing them.


Here’s What to Do to Make Your Food Last Longer in the Refrigerator

  • Check to see if your refrigerator is keeping items cold enough. Set your refrigerator to 4 degrees Celsius or below. If you’re not sure, get a fridge thermometer to make sure everything is in top condition.
  • Make sure your refrigerator isn’t overloaded. This will generate heated pockets, which may cause food to spoil more quickly.
    Use the additional humidity in the crisper drawers to your advantage. Keep leafy greens and other vegetables in the enclosure that will benefit from the excess moisture that accumulates. Set the drawer’s dial to the high-humidity setting and your fruits and vegetables will last longer.
  • Food packaging should not be reused. Transfer your food especially proteinous foods to a fresh, dry airtight container or plastic food wrap once opened.
  • Familiarize yourself with the recommended period for keeping food, including condiments, in your refrigerator. Some foods have a shorter shelf life than you would expect.

Tip: To keep track of when you opened the jars, use a roll of tape and a permanent marker to date them. This will serve as a reminder to consume them so they don’t go stale before their time.


In a Nutshell

Thong Guan plastic food wrap isn’t just for covering food bowls. Plastic wrap can be used in a variety of ways. Fruits, such as bananas, can be wrapped to keep them fresh.

To store herbs and leafy vegetables like lettuce in the fridge, wrap them in plastic wrap. If you are making sandwiches but don’t want to keep them in a container, plastic wrap is great for storing sandwiches.

You can also prevent bottle leaking by covering the mouth of the bottle with plastic wrap before placing the cap. Fruits like cherries, berries, and grapes can also be wrapped to avoid freezer burn.

It will keep the food fresh for a longer period. Wrapping your meals and keeping them at a temperature below 40 degrees Fahrenheit will help your food stay safer for extended periods by inhibiting the growth of bacteria.

Why should we focus on post-consumer recycled resins?

Thong Guan Why focus on post-consumer recycled resins global plastic waste

As Thong Guan progressively adopts the sustainability culture, we continue to engineer and innovate products with post-consumer recycled resins.

The post-consumer recycled (PCR) resin market is projected to reach USD 31,420 million by 2026 (from USD 30,070 million in 2020). 

It is also expected to grow with a healthy growth rate of more than 0.7% from 2021 thru 2026.

With the growing trend of recycled resins market, we look into why PCR and explore the advantages and opportunities of using post-consumer recycled resins.

Defining PCR & PIR Plastic Resins

The ISCC Plus has clearly distinguished the differences between PCR and PIR resins.

Briefly, PCR plastic resins are

  • Plastic materials generated by end-users products 
  • From end-users of households, commercial, industrial & institutional facilities
  • Products that can no longer be of use for their intended purpose
  • Also, materials return from the distribution chain

Why Post-Consumer Recycled Resins & the Climbing Growth Rate of PCR Resin Market

Every year, the global primary production of plastics amounts to a whopping 359 million tonnes

The plastic waste itself, when improperly managed, is at risk of leakage to the environment every year—an estimated 8 million tonnes of plastics enter our ocean every year.

The production of plastics is expected to continue rising steadily.

This means more plastic waste.

That is why it matters to us that we address sustainability as everyone’s responsibility—because it takes more than just one party to make the recycling and circular economy work.

Plastic is undeniably one of the greatest inventions of the last century. Without plastics, many inventions became almost impossible.

Therefore, plastic is not the problem.

Poor plastic waste management is the issue, as indicated in the statistics below.

A considerable percentage of our plastics still end up in landfills where

  • 92% of the collected waste in the United States and
  • 69% across Europe are diverted to landfills or waste incineration plants, and
  • only 14% of the world’s plastics wastes are collected and recycled.

As such, we see more stakeholders—policymakers, governments, manufacturers, companies, and institutions jumping on the PCR resins bandwagon.

Of course, there are other reasons like crude oil prices, Covid-19 global pandemic effects on global production and demand, supply chain and market disruptions, financial impacts, and more.

Though sustainability is not the only reason. But holistically, it impacts the overall business ecosystem and global economy.

However, we want to take the perspective from your company as our customer. 

Here are four reasons why using post-consumer recycled resins in your new products will help your company.

Advantages of Post-Consumer Recycled Resins in Your Packaging Films 

1. Lower your company’s carbon footprint, improve sustainability score, and enhance your ESG goals

Using post-consumer recycled resins can lower your company’s carbon footprint (greenhouse gas/carbon gas emissions) compared to virgin resins in your new products. 

Contrary to general perceptions, using post-consumer recycled resins in your new products versus virgin materials

  • is more cost-effective, and
  • use more energy and emit more carbon.

According to the report published by the Association of Plastic Recyclers (APR), it concludes that using post-consumer recycled resins in your new product reduces greenhouse gas emissions compared to virgin material.

The study has taken into consideration the lifecycle impacts, which means 

  • fuels required to run collection trucks,
  • resources needed at material separation facilities, and 
  • energy to process the materials into flakes and pellets.

Here’s the concluded table showing all 84 categories investigated.


Similarly, the recently published research by Oregon’s Department of Environmental Quality also highlighted that using recycled content has environmental benefits relative to virgin materials. (source:

2. Improve your ROIs and be less dependent on petrochemical market pricing volatility

The petrochemical market is volatile.

This means crude oil prices will continue to increase (as seen throughout most of 2018). As such, plastic resins price is subjected to surges constantly. 

Fortunately, the cost of PCR resins is much more stable compared to virgin resins.

So, you don’t have to subject yourself to the volatility of the market.

Also, let us help you with ‘thin’ gage films that also reduces the amount of virgin resins required in your films.

Thus, improving your total costs and return on investment as well.

Furthermore, under the law of supply and demand, more PCR resins adoption means marginalising the PCR resins cost in the long run.

3. Enjoy the same, if not better, benefits as pure virgin materials films

At Thong Guan, we constantly preach about, “there is no such thing as wrong film, only inferior vs quality films.”

And achieving quality films means meeting the film requirements of our customers based on their needs—as we have detailed how we can achieve that in our #RecycledPlasticsSeries articles, comprehensively.

As such, we can proudly say you will still enjoy the benefits of all the functionalities of standard virgin-material films, while achieving your sustainability.

4. Be more regulatory friendly & exempt from taxes 

Lastly, due to the demand for sustainability adoption, regulations favour recycled content packaging and products. 

PCR resins are becoming increasingly regulatory friendly.

Therefore, with sustainable packaging on your inventory, you can meet environmental impact regulations post on your company by your local government.

Additionally, you can get the plastic tax exemption if you are shipping to the UK with plastics packaging that contain more than 30% recycled plastic

This will take effect from 1 April 2022 onwards.


There are many more benefits of using post-consumer recycled resins packaging to add to the top four benefits we believe matter to your business. 

For instance, 

  • better branding
  • better customer relations in fulfilling consumers demand for sustainable products
  • better margins with higher price points, again due to the demand
  • long term sustainability for economic growth

All the more reasons why we should focus more on post-consumer recycled resins.
