Hey there! I’m a supplier of Food Packaging PE Coated Series. You might be wondering how we measure the performance of these products. Well, let me break it down for you. Food Packaging PE Coated Series
1. Barrier Properties
One of the most important aspects of food packaging is its ability to keep the food fresh. PE coated series are great at this, but we need to measure just how good they are.
Oxygen Transmission Rate (OTR)
Oxygen can cause food to spoil, so we measure how much oxygen can pass through the packaging. We use special equipment to create a controlled environment. On one side of the packaging sample, we have a high – oxygen atmosphere, and on the other side, a low – oxygen one. Then we measure how much oxygen moves from the high – oxygen side to the low – oxygen side over a certain period. A lower OTR means the packaging is better at keeping oxygen out, which is great for food like chips or nuts that can go rancid when exposed to oxygen.
Water Vapor Transmission Rate (WVTR)
Moisture is another enemy of food. Too much moisture can make dry foods soggy, and too little can make moist foods dry out. To measure WVTR, we put a sample of the packaging in a chamber with a specific humidity level on one side and a different humidity level on the other. We then measure how much water vapor passes through the packaging over time. A low WVTR indicates that the packaging can keep the right amount of moisture in or out, depending on the food it’s meant to hold.
2. Mechanical Properties
The packaging needs to be strong enough to withstand handling and transportation.
Tensile Strength
We test the tensile strength by pulling a sample of the packaging material until it breaks. This tells us how much force the material can handle before it fails. For example, if we’re packaging heavy items like cans or large packages of food, we need a material with high tensile strength to prevent tearing during shipping.
Puncture Resistance
Food items can have sharp edges or corners that might puncture the packaging. To measure puncture resistance, we use a probe to push through the packaging material at a controlled speed. The amount of force required to puncture the material gives us an idea of how well it can protect the food inside. This is especially important for products like frozen foods, which often come in hard, angular packages.
3. Chemical Compatibility
The packaging should not react with the food it contains.
Migration Testing
We do migration testing to see if any chemicals from the packaging can migrate into the food. We place a sample of the food and the packaging in a controlled environment for a certain period. Then we analyze the food to see if there are any substances from the packaging. This is crucial because some chemicals can be harmful if they get into the food. For example, if the packaging is made with certain plasticizers, we need to make sure they don’t leach into the food.
4. Printability
If we want to put labels or branding on the packaging, it needs to have good printability.
Ink Adhesion
We test ink adhesion by applying ink to the packaging surface and then using a tape test. We stick a piece of tape on the printed area and then peel it off. If the ink comes off with the tape, it means the ink adhesion is poor. Good ink adhesion ensures that the labels and branding stay on the packaging throughout the product’s shelf life.
5. Heat Resistance
Some food packaging needs to withstand heat, especially if the food is going to be heated in the package.
Heat Seal Strength
When we seal the packaging, we need to make sure the seal is strong enough. We measure the heat seal strength by pulling apart the sealed area of the packaging. A strong heat seal ensures that the food stays inside the package and that no air or moisture can get in.
Thermal Stability
We also test the thermal stability of the packaging. We expose the packaging to different temperatures and see how it behaves. For example, if the packaging is going to be used in a microwave, it needs to be able to withstand the heat without melting or releasing harmful chemicals.
6. Cost – Effectiveness
As a supplier, we also need to consider cost – effectiveness.
Material Cost
We look at the cost of the raw materials used to make the PE coated series. We try to find a balance between the quality of the packaging and the cost. For example, if we can use a slightly cheaper material without sacrificing too much in terms of performance, it’s a win – win for us and our customers.
Production Efficiency
We also consider how efficiently we can produce the packaging. If the production process is too slow or requires a lot of energy, it will increase the cost. We constantly look for ways to improve our production processes to make them more cost – effective.
Why It Matters to You
These performance measurements are not just for our benefit. They matter to you, the customer. When you’re buying food packaging, you want to make sure that it can keep your food fresh, protect it from damage, and look good on the shelf. By measuring these performance factors, we can ensure that our Food Packaging PE Coated Series meet the highest standards.
