Laravel 5 - Accessing collection values in view

I am building an order management system in Laravel 5.3. I am storing the orders in two different tables - orders, order_content. The first one contains order's main data, the other - content. I am using Crinsane's Shopping Cart package for managing order contents. The order contents table fields: identifier, instance, content. Content field contains collection with the specific order content, which is searialized.

I add each order's content in collection and then pass that collection to view. My problem is I dont know how to access the collection's items in view... Controller:

 public function showByDate()
{
    $datetime_today = new DateTime('now');
    $date = $datetime_today->format('Y-m-d');

   /* $orders = Pasutijums::where('pasutijums_uz', '=', $date)
        ->where('ir_apstiprinats', '=', 1)->get(); */

    $collection = collect();

    foreach($orders as $order)
    {
        $order_contents = DB::table('order_content')->where('instance', '=', $order->pasut_num)->get();

        foreach($order_contents as $content)
        {
            $collection->push(unserialize($content->content));
        }

    }


    $items = $collection->all();

    return view('admin.kopsavilkumi.pec-datuma')
        ->with('orders', $orders)
        ->with('date', $date)
        ->with('items', $items)
        ;



}

When I dd($collection) I get:

Collection {#292 ▼
    #items: array:2 [▼
    0 => Collection {#307 ▼
        #items: array:2 [▼
        "da951a56dc871db7b48a41f7d14b007b" => CartItem {#308 ▼

                    -associatedModel: null
                    -taxRate: 0
    }
  ]
}
1 => Collection {#306 ▼
                #items: array:1 [▼
                "da951a56dc871db7b48a41f7d14b007b" => CartItem {#312 ▼

                        -taxRate: 0
    }
  ]
 }
]
}

View:

 @foreach($items as $item)

       @foreach($item as $order)

           <tr>
               <td class="text-primary">  </td>
               <td>  </td>
               <td>  </td>
           </tr>


       @endforeach

@endforeach
