How to choose the suction head:

First, no enzyme suction material

The suction cups currently on the market are basically made of polypropylene plastic (colorless transparent plastic, high chemical inertness, wide temperature range). However, if it is the same polypropylene, the quality can also vary greatly: high-quality suckers are usually made of natural polypropylene, while low-cost suckers may use recycled polypropylene plastic. In addition, most suckers have a small amount of additives added during the manufacturing process. Common ones are:

1. Color developing materials. In the market, it is usually called blue gun head (1000ul) and yellow gun head (200ul), and the corresponding color developing material is added to the polypropylene.

2. Release agent. After forming, help the sucker to quickly separate from the mold. Of course, the more additives, the higher the possibility of adverse chemical reactions during the transfer process. Therefore, biofount Vander biological company's production and development is suitable for enzyme-free suction heads, and the general models do not add additives! The color of transparent water. However, due to the high demands on the production process, there are few additive-free suction heads on the market.

Second, the packaging form of no enzyme suction head

The packaging form of the suction head mainly has bags and boxes. In relatively mature markets, boxed packaging is the majority; In China, bagging is now mainstream - mainly because it's cheap. The so-called bagging is to put the suction head into a plastic self-sealing bag of 500 or 1000 pieces per bag. Most users will purchase bagged suction cups and then manually place them into the sucker case. Although China's labor is relatively cheap, it also increases the chances of attracting pollution! In addition, in recent years, a new form of packaging has emerged, that is, supplementary packaging. The suction head requires less storage space, greatly reducing the use of plastic, to achieve the purpose of environmental protection.
