Keeping Packs Clear When Fresh Food Meets Cold Air

 

Fresh produce appears at its best when it can be seen clearly; however, small water droplets frequently ruin that view within a cold pack and as a result shoppers leave without making a purchase. A solution to this problem is the Antifog BOPP Film, which keeps the surface clear even when the cabinet is cold.

What Causes Fogging

Vegetables, fruits, and baked goods emit warm, moist air. On coming into contact with a cooler surface this forms droplets that scatter light and thus create a cloudy appearance. As ordinary polypropylene sheets are naturally water repellent, the droplets remain spherical. In the case of a treated sheet the surface tension is reduced by means of a special additive and the water spreads to form a thin transparent layer.

Where It Is Used                     

This substance is commonly used for packing salads, herbs, and mushrooms, and coatings for bakery trays and sandwich wraps. Mostly it is applied in cold storage rooms and supermarket displays as it enhances visibility and allows staff to identify any spoilage. As customers tend to trust what they can see many retail chains have asked for antifog film.

Points to Remember

The treatment may be used on one side or on both sides and the right side should be selected for the inner surface of the pack. Before a grade is given, performance is tested at a number of different temperatures. The heat sealing must be enacted at the correct settings to make sure that the seals remain tight. Antifog BOPP Film is available in a variety of thicknesses so that the weight of the pack can be adjusted. The rolls should be stored away from direct sunlight and excessive heat. Guidance regarding the test data and shelf life should be obtained from the supplier.

Closing Note

Packings that are clear and transparent are noticed and selected; a slight change in material can result in a big increase in sales. For any business which sells fresh products, antifog film is a practical solution.

Food Packaging Film Perks How It Helps Maintain Food Quality & Freshness

 

A packet of chips has been sitting on the shelf for months, yet it still delights our taste buds. Such small miracles are made possible thanks to science and technology – more precisely, by material science and JPFL Films is happy to dedicate its efforts every day to this task and provide a simple explanation.

Freshness Starts With Barrier                

Oxygen, moisture, and light are the 3 prime enemies of food packaging. Any packaging film for food is engineered to keep them away in appropriate proportions. Snacks require a stronger barrier against moisture while bread requires some breathability. Dairy products have to be protected from light, and the right balance is selected for each product individually.

Layers With Different Jobs

Modern flexible food packaging is rarely a single-layer film. On the contrary, several layers are often combined to allow different tasks to be performed. One layer carries the print while another provides strength and a third creates the seal that will close the pack. Thin pouches can thus protect food for many months.

Looks Matter Too

Shoppers make a decision almost instantly and bright colors and striking images are expected. A variety of special effects such as gloss or matt can also be applied to match the brand. The product is visible through the windows in the film and printing is done on properly treated surfaces, never overlooked.

Safety Comes First

Materials that come into contact with food must undergo stringent tests. The raw materials are selected from approved suppliers. Clean production areas are a must. Migration tests are performed to ensure that no unwanted substances enter the product and batch records are maintained so that each roll can be accounted for.

Cutting Food Waste

A good pack can do more than look beautiful. Spoiled food is a global problem and better protection means less waste. Long shelf life also enables more distant markets to be reached. Small improvements in performance can therefore have a major impact.

Doing More With Less

Lighter packs consume less plastic and save on transportation prices. Flexible packaging film is becoming thinner every year without sacrificing aid. Production waste is collected and recycled whenever possible and designs that facilitate recycling are also being explored.

Final Thoughts

Next time a pack is opened with a satisfying crackle a thought should be spared for the material inside. Quiet work is done by food packaging film every single day. JPFL Films is proud to be part of that story.
