Portal webpages in multiple languages

I have a custom web page which I'm showing the entity list in the form of tiles using the web template like below:

{% for item in entityview.records %}							  								
									
	<item>										
	   <div id="deviceList" style="display:inline-block; width:250px;">								
		Model: {{ item.model }} <br/>
		Date Purchased:{{ item.purchasedate }}<br/>
		Serial Number:{{ item.deviceserialnumber }}<br/>
	    </div>
	</item>
	
{% endfor %}

My issue is : This portal has to be enabled for 15 languages. If this a OOB entity form, I'd have used entity metadata to add the labels in different languages.

But this is a custom page. The only solution I could find is to create 15 page templates and 15 web templates and put them in the corresponding localized content of the web pages. 

Is there any other solution than this? A more effective and less regressive way of doing things?
