The food packets and pouches in the store shelves have something in common. Most of them are either made of aluminum foils or have a coating of aluminum or other metals on polymer foils. So, there is either a metalized ถุงฟอยด์ or a aluminum ถุงฟอยด์. These bags are normally used to store food products. You can get these bags to store and carry milk and other dairy products too. The use of such bags and pouches is so huge that it is difficult to think of an item that is not stored or carried in these bags.
Products stored and carried
A host of products stored in ถุงฟอยด์s,including aluminum ถุงฟอยด์s and metalised ถุงฟอยด์s. This includes processed food and beverages like chips, nuts, tea, coffee etc, daily products like milk, cheese, yoghurt etc, noodles and other fast food items etc. Apart from food products the uses of ถุงฟอยด์s are to carry and store other products too. This includes electronic and electrical items like electrical capacitors, smartphone accessories etc.
Benefits of aluminum ถุงฟอยด์s
Such bags prevent the entry of moisture and air, and therefore can keep food fresh for a long time. So you can get various shapes of ถุงฟอยด์s. One of the most popular types is the flat bottom stand up pouch which occupies less shelf space. These pouch bags are frequently used to store food products.
Manufacturers use foil pouches for products that require multiple layers like layers of aluminum. They use the metal layer in the inner part of the pouch. Since they make the innermost part of the packaging, they need to be very hygienically manufactured and nontoxic. Aluminum is the preferred choice for ถุงฟอยด์ inner coating, since it can protect the content from extreme variations of heat. Moreover, these bags don’t permit much moisture transmission. That is why these bags are popular for use in packaging of cereals since they prevent infestation by pests. These pouches also help the food product to keep its aroma intact. These pouches are also used for packing surgical blades and other surgical and medical instruments. This is because the packs help keep the equipment in complete air tight condition. These pouches have 3 to 4 layers of aluminum or other metal foil. The higher the number of layers, the stronger is the ถุงฟอยด์. However, this also makes the bag expensive. You need such bags for packing products like milk and other liquid items.
These are different from ถุงฟอยด์s. They are made by coating polymer layers with layers of metal such as aluminum. These bags too can be found in flat bottom stand up shapes. The advantage with such bags is that since these are opaque, they don’t allow any light inside. So if the product is sensitive to light you need to use a metalized ถุงฟอยด์. They too put up strong barriers against moisture and oxygen. Moreover, such bag is stronger than ถุงฟอยด์s and are resistant to puncture.
