Starting from June 28th, These Power Banks Are Banned from Boarding! The Plastics Industry Embraces New Opportunities

I. Core Control Points of the New Regulations  

1. Povinná požiadavka na certifikáciu 3C: Všetky energetické banky musia schváliť certifikáciu národnej 3C a ich známky musia byť jasne identifikovateľné. If the marks are worn, blurred, or their authenticity cannot be verified, the power banks will be prohibited from being carried.  

2. Comprehensive Ban on Recalled Products: Recently, many brands have recalled some products due to safety hazards in their battery cells. The relevant models or batches are strictly prohibited from being carried.  

3. Restrictions on Capacity and Parameters: Power banks with a rated energy exceeding 160Wh are strictly prohibited from being carried; those with 100-160Wh need prior approval from the airline (each person is limited to 2). Products without marked parameters are all prohibited from transportation.  

Varovanie o bezpečnosti: Experimenty ukazujú, že teplota skratenej energie môže stúpať na viac ako 400 ℃ do 15 sekúnd, čo sa dá ľahko zapáliť okolité položky. The change in air pressure during flight will further aggravate the risk!  

Tips for Identifying 3C Marks:  

- Genuine Mark: White base + black pattern, with a three-dimensional texture when observed against the light;  

- Fake Mark: No three-dimensional effect, with blurred patterns that are easy to fade.  

II. Frequent Safety Incidents of Power Banks, Many Brands Plunge into Recall Crisis  

Since this year, incidents of power banks catching fire or smoking on planes have occurred repeatedly. Oznámenie Štátnej správy pre reguláciu trhu vo februári ukázalo, že pri náhodnej kontrole 149 šarží mobilných výkonových produktov na 9 platformách vrátane JD.com a TMall sa zistilo, že 65 šarží nie je nekvalifikovaných. The problems are concentrated as follows:  

- 4 batches are suspected of being counterfeit, and 5 batches have false manufacturer names and addresses;  

- 3 batches failed the high-temperature external short-circuit test;  

- 35 batches failed to meet the conversion efficiency standard, 32 batches exceeded the radio interference limit, and 20 batches had insufficient effective output capacity.  

III. The Plastic Industry Chain Welcomes New Development Opportunities  

The structure of a power bank mainly includes three major components: battery cells, circuit boards, and casings. Among them, the battery cell, as the core component of the power bank, is mainly composed of lithium-ion batteries or lithium-polymer batteries. In the upstream of the lithium battery separator industry chain, raw materials include polyethylene, polypropylene, coating materials (such as PVDF, aramid, etc.), and additives.  

Plastic is one of the commonly used materials for making power bank casings, which are generally processed and formed through injection molding. Takéto materiály majú nielen vlastnosti ľahkej hmotnosti a robustnosti, ale tiež spĺňajú potreby flexibilných a rozmanitých návrhov vzhľadu. Common plastic materials include PC (polycarbonate) and ABS (acrylonitrile-butadiene-styrene copolymer).  

In addition, some new composite materials are also used in the manufacture of power bank casings, which can reduce the product weight while ensuring strength and durability. Take flame-retardant PC/ABS alloy as an example. It is formed by compounding PC and ABS through an alloying process, and has properties such as high strength, high rigidity, and toughness. Dokáže vydržať určitý stupeň vonkajšieho nárazu bez praskania alebo zlomenia, čím účinne chráni vnútornú batériu, dosku obvodov a ďalšie komponenty energetickej banky spôsobenej poškodením spôsobeným kolíziami, 挤压 atď. Jej hodnotenie spomaľovača horenia môže dosiahnuť UL94-V0 1,5 mm, pričom charakteristika samovraženia pri požiari, ktoré môže účinne spomaliť spread z ohňa.  

With the ban on unqualified power banks, the demand for compliant products has surged, driving the plastic industry chain to embrace transformation opportunities. Od základných surovín po upravené kompozitné materiály získajú príslušné podniky prírastkový priestor v oblasti výroby energetických bánk.
