What is the plastic film outside the photo used for and what is it called?

It’s called plastic sealing.

It is necessary to seal the album photos in plastic. Since the surface of the laminated printed matter in the photo album has a thin and transparent plastic film, the surface is smoother and brighter. This not only improves the gloss and fastness of the printed matter, but also extends the service life of the printed matter. At the same time, the plastic film also acts as moisture-proof , waterproof, anti-fouling, wear-resistant, fold-resistant, chemical corrosion-resistant and other protective functions.

Photos that have been plasticized will last longer, while photos that have not been plasticized will be stuck together in about ten years and will no longer be visible. Over-molding means that after the photo is printed, a thin layer of plastic is pressed on the front and back of the photo. After over-molding, the photo will be harder and will not leave marks on the photo when you touch it, and dust will not stick to it. Convenient for photo collection.

Methods and common sense for saving album photos:

1. Save location. First of all, make sure there is no direct sunlight in this location, which will cause the photos to change color, but it will not work in humid places, which will cause some paper products to deform and wrinkle. If the home is too humid, put some desiccant, such as melon seeds, snow cakes and other foods. Desiccant in the. Also, be careful not to put pressure on the bottom of the box, as this may crush crystal photo album products.

2. Common sense when appreciating photo albums. Pay attention to handling it with care when looking at it. Especially for crystal photo albums, you should not only be careful not only to break them, but also to pay attention to wear and tear. Album ornaments made of this material will lose their transparency after wear, resulting in unclear visibility.

3. Deformation processing: Photo albums are usually made of paper or plastic, so sometimes they are deformed due to pressure or other factors. Don’t worry if this happens. Sky Photography’s photo albums are all standard photo albums. For paper, just lay your album flat and press it with something heavy, like a dictionary. It shouldn't take long, but the most important thing is to check where you saved it to see if it's too damp. Or if it is pressed down by something, you need to take good care of it.

4. Water treatment and maintenance. Photo albums placed in the living room may have more problems after having children. For example, if they get wet by water, they need to be wiped dry immediately to prevent water from seeping into the photos. If it is dirty, you can use a wet rag to wipe it, but you cannot wipe it with a wooden photo frame, as it may cause the frame to deform and crack. Many people now make crystal or metal photo frames. Just be careful not to get the photos wet.

5. The hanging position of the photo frame. The maintenance of photo frames has basically been discussed above. Finally, let’s talk about the hanging position. It is best not to hang it on the bedside. Today’s photo frames are relatively large and heavy. To avoid falling and hurting people, they can be hung on other walls. It is best to have a support at the bottom, because the crystal photo frame is indeed not light.
