I got product collection in my custom template using following code

 $objectManager = \Magento\Framework\App\ObjectManager::getInstance();
  $productCollection = $objectManager->create('Magento\Catalog\Model\ResourceModel\Product\Collection');

foreach ($productCollection as $product) {
           $product_id=$product['entity_id'];
           echo $_product->getName();
