     */
    protected $productFactory;
    protected $resultPageFactory;

    public function __construct(
        \Magento\Framework\App\Action\Context $context,
        \Magento\Framework\View\Result\PageFactory $resultPageFactory,
        \Magento\Catalog\Model\ProductFactory $productFactory,

        parent::__construct($context);
    }
    public function execute()
    {
        try {
            $postedData = $this->getRequest()->getPostValue();
            //echo "";print_r($postedData['multi_add']);exit;
            foreach ($postedData['multi_add'] as $productId => $qty) {
                if($qty>0){
                    $params = array();
                    $params['qty'] = $qty;//product quantity
                    $_product = $this->productFactory->create()->load($productId);
                    if ($_product) {
                        $this->cart->addProduct($_product, $params);
                        $this->cart->save();
                    }

                }
            }
           
            $this->messageManager->addSuccess(__('Add to cart successfully.'));
        } catch (\Magento\Framework\Exception\LocalizedException $e) {
            $this->messageManager->addException(
                $e,
                __('%1', $e->getMessage())
            );
        } catch (\Exception $e) {
            $this->messageManager->addException($e, __('error.'));
        }
        /*cart page*/
        $this->getResponse()->setRedirect('/checkout/cart/index');


    }
}

Re: Add multiple simple product to cart not working

You need to keep $this->cart->save() function outside the loop to correct add a multiple products.

Final code,

<?php
namespace Kite\Boxes\Controller\Category;
class Addpack extends \Magento\Framework\App\Action\Action {

    /**
     * @var \Magento\Checkout\Model\Cart
     */
    protected $cart;
    /**
     * @var \Magento\Catalog\Model\Product
     */
    protected $productFactory;
    protected $resultPageFactory;

    public function __construct(
        \Magento\Framework\App\Action\Context $context,
        \Magento\Framework\View\Result\PageFactory $resultPageFactory,
        \Magento\Catalog\Model\ProductFactory $productFactory,
        \Magento\Checkout\Model\Cart $cart
    ) {
        $this->resultPageFactory = $resultPageFactory;
        $this->cart = $cart;
        $this->productFactory = $productFactory;
        parent::__construct($context);
    }
    public function execute()
    {
        try {
            $postedData = $this->getRequest()->getPostValue();
            //echo "";print_r($postedData['multi_add']);exit;
            foreach ($postedData['multi_add'] as $productId => $qty) {
                if($qty>0){
                    $params = array();
                    $params['qty'] = $qty;//product quantity
                    $_product = $this->productFactory->create()->load($productId);
                    if ($_product) {
                        $this->cart->addProduct($_product, $params);
                    }

                }
            }
            /* keep this outside the loop */
            $this->cart->save();
           
            $this->messageManager->addSuccess(__('Add to cart successfully.'));
        } catch (\Magento\Framework\Exception\LocalizedException $e) {
            $this->messageManager->addException(
                $e,
                __('%1', $e->getMessage())
            );
        } catch (\Exception $e) {
            $this->messageManager->addException($e, __('error.'));
        }
        /*cart page*/
        $this->getResponse()->setRedirect('/checkout/cart/index');


    }

        $this->getResponse()->setRedirect('/checkout/cart/index');


    }
}

also add following code in your module 

etc/frontend/sections.xml 

so it update minicart as well.

 <?xml version="1.0"?>
<config xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance"
        xsi:noNamespaceSchemaLocation="urn:magento:module:Magento_Customer:etc/sections.xsd">
    <action name="category/category/addpack">
        <section name="cart"/>
    </action>
</config>
category/category/addpack

Here your action name.
