Plastics are among the most widely used synthetic polymer materials, alongside rubbers and synthetic fibers. Their applications have become deeply embedded in various sectors of the national economy. Globally, the annual production of plastics has surpassed 1.6 billion tons. However, there is still a significant variation in how plastic products are consumed across different industries. Currently, the packaging and construction industries represent the largest markets for plastics, with packaging materials taking the lead. Approximately 30% of all plastic products are used in packaging, which is nearly 10% more than the total amount used in building materials. This makes plastic packaging not only the most common but also the most efficient application.
Compared to traditional materials like glass, metal, and wood, plastic packaging has become the second most popular after paper. Moreover, it's growing at a faster rate than any other type of packaging material. Clearly, plastic packaging plays a vital role in the national economy. Yet, as a relatively new material, plastic has not fully realized its potential. Many of its advantages remain untapped, and some performance limitations are still not well understood, leading to challenges in practical use. Therefore, it's essential to objectively evaluate and study plastic packaging materials in research, production, and application to ensure their continued development.
Other notable types of packaging plastics include polyvinylidene chloride (PVDC), ethylene-vinyl alcohol (EVOH), high acrylonitrile (PAN), and polyvinyl alcohol (PVA). These materials offer excellent barrier properties against non-polar gases such as carbon dioxide and nitrogen, along with strong oil resistance.
PVDC, in particular, is highly moisture-resistant and is considered ideal for food packaging. It can be applied as a solution or emulsion on films or hollow containers to form a thin protective layer that effectively blocks oxygen and moisture. Despite its high cost and processing difficulties, as well as environmental concerns from incineration, PVDC remains widely used in packaging.
EVOH is regarded as one of the best barrier plastics, especially in high-barrier applications. It doesn't release harmful substances when burned, making it an environmentally friendly option. Though expensive, it’s commonly used in premium composite bottles, multilayer films, and sheet barriers.
High acrylonitrile resins and PVA are challenging to process, limiting their widespread use. PAN is often used for biaxially oriented bottles with good barrier properties, while PVA is mainly used in film production. Biaxially stretched PVA film serves as a base for high-barrier composite films, while non-stretched PVA film is used for high-quality packaging bags, offering excellent transparency, gloss, and printability. It also provides anti-static properties, avoiding issues like dust accumulation that are common in regular plastic bags. This makes it ideal for packaging delicate items like clothing, ensuring a clean and visually appealing display.
Nail Brush...WHICH BRUSHES FOR WHAT MATERIAL TO CHOOSE CORRECTLY? GEL - for gel modeling we choose brushes suitable for scooping UV / LED gel, so it is necessary to use a flat brush with which you can easily apply UV / LED gel on your nails and shape it into the right shape. There are several hair sizes and types. Furthermore, 2 shapes are used for gel modeling, either flat straight or flat oval. SAMINA Nails offers several types, which you can find HERE.
POLY GEL - a special brush is used on the poly gel, which has a spatula at one end to gain mass and a brush at the other end for shaping. We also offer a device that has a silicone tip at the ends, which can be used to shape the poly gel. We offer a poly gel brush HERE.
Â
ACRYLIC - round brushes with a tip are used for modeling acrylic nails. The most common sizes are 8 and 10, and the finest hairs that use liquid are perfectly used for these brushes. We offer these brushes HERE.
NAIL ART - there are a lot of brushes for nail art and decorating. The most important brush that no one should miss is the detailer, or extra thin brush, which is suitable for detailed work around the cuticle and nail walls. You can also paint a French manicure or thin lines with it. It's simply a brush you have to have. Another very popular is, for example, a brush for ombré, or a gradual transition of colors, for glitter and many others. You can find our offer HERE.
BRUSH CARE
If we want the brush to last us as long as possible, it is also necessary to take good care of it.
Never leave the brush in the water or detergent for too long - the brush head may come loose or the sleeve may start to rust
Clean the brush thoroughly - head and sleeve
Dry the moisture with a clean cloth or napkin
Place the brush upside down to dry
Dry at room temperature

Clean the brushes you use on UVLED gels properly and store them in a dark place. This will prevent direct light from curing the remnants of the gel left on the brush.
