The weather is getting hotter and the sunshades are starting to sell. Yesterday, the reporter visited a number of supermarkets and shopping malls selling parasols in Hong Kong. They found that the prices of umbrellas were very different. Many sunshades that looked very beautiful did not have sunscreen labels at all.
The quality is uneven and the price difference between the umbrellas is very large.
In many large shopping malls, the umbrella tags sold in the malls have the words “UV protection”, and the price ranges from 39 yuan to 198 yuan. Among them, only one brand of umbrella tag is marked with "sun protection factor: UPF40+, UVA is greater than 5%", and the other two brands of "parasols" on the shelf are not marked with sun protection factor on the outer packaging and label. .
Compared with cheap umbrellas, the higher-priced parasol fabrics are thicker and the labels are more detailed. In addition to the words “UV protection umbrella” or “anti-UV”, the product descriptions are mostly marked with a sun protection index. "The higher the price, the stronger the UV protection function of the coating on the sun umbrella surface. Those ten umbrellas of twenty dollars, the surface of the umbrella is coated with a layer of inferior reflective paint, even the sun is not blocked, let alone prevent Ultraviolet light.
Deep color, thick fabric and good sun protection effect
The higher the price of the umbrella, the better the effect of UV protection? Is there a standard for the “sun protection” of the umbrella? In this regard, the staff of the Quality Supervision Bureau of Yantai City stated that according to the national standard “Assessment of UV Protection Performance of Textiles”, only UPF (UV protection coefficient value) is greater than 30, and UVA (long-wave ultraviolet) transmittance is less than 5%, it can be called UV protection products, "both indispensable." The label of the UV protection product shall be marked with the number of "Assessment of UV Protection Performance of Textiles" and the protection rating "UPF30+". When the UPF is between 40 and 50, the protection rating is “UPF40+”; when the UPF is greater than 50, the UV protection performance of the product is excellent, and the protection rating is “UPF50+”.
